MS Classic World Data Slop

What's counted

• Damage, accuracy and crit use the COT2 client formulas and per-level skill tables.
• SP: 1 at each job advancement plus 3 per level. 1st job gets 61 (levels 10–30) and those stay in 1st job skills; 2nd job SP can't go back into them (per meowdb).
• Count buffs adds Rage, Meditation, Focus, Bless, Steal's Attack Power (Bandit), Magic Armor / Iron Body / Iron Will defense and your booster if they have points.
• Attack speed: meowdb's measured times per weapon speed (e.g. speed 6 = 810 ms, 4 = 720 ms); every Magician spell takes 810 ms whatever the weapon. Booster moves your weapon 2 speeds.
• Final Attack is counted only when it helps: each proc plays its own attack (~0.6 s), so on one monster it can cost damage. Hunter's fires 3 arrows. Axe Mastery's bleed and Poison Breath's poison add their damage over time.
• HP and MP follow meowdb's measured gains per level and per job advancement, plus Max HP / Max MP Increase.
• Armor (optional): pick pieces per slot; their stats count everywhere on this tab. Upkeep = potions and ammo per hour while attacking nonstop, at shop prices.
• Copy link makes a link that opens this exact build.
• Import from screenshots reads the game's windows in this page (nothing is uploaded): level and STR/DEX/INT/LUK from the stat window, worn items by their icons, skill levels from the skill window (one screenshot per skill tab; scroll and add more if the list is long). The stat window shows totals, so the read gear's stats are taken off to get your AP. Gear counts as its base stats (an average drop); scrolled or above-average gear adds more, so fix the numbers in the review if you know them. Screenshots add up in any order; ✕ removes one, Reset clears them all. PNG screenshots work best; a game window that's been smoothly resized (not 100% or 200%) may not read.
• Auto build spends every point: first where it adds the most damage after misses, then passives, then buffs. Skills follow the game's prerequisites.

Not counted or estimated

• Scrolls and party buffs. Without armor picked, W.DEF is your STR's share plus skills only.
• 3rd job skills, since 3rd job isn't in the launch. Once every 2nd job skill is maxed, extra SP shows as spare.
• Final Attack's own attack time is fitted to meowdb's Fighter numbers (0.88 × your weapon's attack time).

What it does

• Goes level by level from your level to your goal and builds a list to follow: where to train, which quests to do, how long each takes.
• Your character at each level is the Character Builder's default: best weapon you can use, AP and SP spent by the Auto buttons.
• Class guides (default: build + training maps, levels 1–70): uses meowdb's Warrior, Magician, Bowman, Thief and beginner guides instead:
  • their SP order and AP per level (each level-up is listed under the step it happens in), their shop weapons and gear, free advancement weapons (Beginner's Garnier), Arrow Blow over Double Shot;
  • their Training Advisor maps for each level band (checked for sure hits, 2-hit kills, danger and the walk to town, which this model doesn't check), with the model's fastest map shown when it differs. "Build only" keeps the build but lets the model pick maps;
  • citizenship town at 12, and Wolbi stars or Bronze arrows from 25 (they unlock at citizenship grade 3: level 22 plus 2,000 contribution; reaching it by 25 is an assumption);
  • future Bandits level with a claw and Lucky Seven ("Sindit") and reset their SP at 40 (Cash Shop, 7,000 NX) to switch to daggers, as the Bandit guide does;
  • levels 30–70: each 2nd-job guide's SP order, AP rules, weapons every 10 levels and Training Advisor maps every 5 levels. Their Forgotten Hollow picks are skipped (not at launch). Above 70 the leftover SP and the weapon are picked by the model.
• Quests + grinding: does each quest as it unlocks and grinds in between. Each quest shows how its EXP per hour compares with grinding; tick "Only quests faster than grinding" to keep just those.
• Most rewards: every quest that pays mesos or items, Must do picks first, then lowest level and highest reward value. Items with no known source aren't timed ("+ other items").
• Reward value = quest mesos + what its items sell to NPCs (pick-one: the best; random: the average). That's a floor; rated items sell for far more to players.
• Quests only: every quest it can time, lowest level first, until they run out. Grinding only: maps only.
• Item drops: drop rates aren't in the game files, so the plan assumes 30% per kill by default; slide it from 10% to 35% to test better or worse luck. At 30%, a quest needing 20 Octopus Legs costs about 67 Octopus kills.
• Collecting ahead: while grinding, drops for quests up to 5 levels ahead go in your bag, even before you accept the quest (assuming these drop without the quest, as guides advise saving them). Maps get credit for the farming those drops save later, so the plan may pick a map a bit lower in EXP/hr when its drops pay off. Grind steps list what you collect; quest steps show how many are already saved.
• Valuable quests (Sauna Robe, Icarus Cape, Work Gloves...) are marked with their rating and why players rate it. The ones the plan can't time (items with no known source, or skipped by your mode) appear as side tasks at the level their chain starts. Picks come from community guides; see the Quest Database.
• Quests more than 5 levels under your current level count as already done or skipped. Quests with no EXP are skipped unless a later quest needs them.
• It stays on its current map unless another one is more than 10% better, so you don't hop maps every level.
• Grind rows show the map's danger for your character (one hit as a share of Max HP, no armor, and how often it lands) and the portals to potions.
• If it's crowded: each grind row lists up to 2 backup maps whose monsters average within 5 levels of the pick and give at least 60% of its EXP/hr (same model, from the game files). The percentage is their EXP/hr against the pick; a backup can be faster when the pick is a guide map or wins on quest drops or a shorter walk. With class guides on, backups can be maps the guide didn't pick.
• Mesos: monster meso drops (player reports on meowdb, ~2 per monster level where nobody has reported) and quest mesos, against weapons at NPC shop prices and potions and ammo while grinding. The potion bill assumes skills on every attack; quest potions are taken off it. Selling loot isn't counted.
• Copy link makes a link that opens this exact plan.
• Party: grinding uses your share of the map plus the party EXP bonus (see Where to train). Quests stay solo. The Kerning Party Quest shows up at 21 as an optional step.
• Goes up to the level-100 cap with 2nd job (3rd job isn't at launch). EXP per level is the launch client's table (levels 90-99 cost 2.1× the level before).

Times are estimates

• Grinding times come from the "Where to train" model (solo unless you pick a party).
• Average player takes 1.5× the model time, Relaxed 2×: crowded maps, potions, breaks. Check: at 1.5× the plan takes about 3–4.5 h for 10→20 and 9–10 h for 20→30; meowdb reports COT2 testers took 3–4 h and 8–9 h.
• Travel counts: every move between maps is its own step with the route (walk, cab), so you can tick it off. The plan knows where you are. A quest means walking to its NPC, to the closest good map for each monster it needs, and back. Grinding maps far from you lose points for the walk. Crossing one map ≈ 30 s, a cab between towns (Lith Harbor, Henesys, Ellinia, Kerning City, Perion, Sleepywood) ≈ 45 s, talking to an NPC ≈ 1 min (30 s for the same NPC again). All guesses.
• Quest kills also wait on the map's respawns: few of a monster on a map means slower kills there. Kill EXP from quests counts.
• AoE build (default): each level's character uses its best multi-target attack when the job has one: Slash Blast, Arrow Bomb, Iron Arrow, Thunder Bolt, Poison Breath (Power Knockback is skipped: it pushes monsters away). Thieves, 1st job Bowmen and 1st job Magicians have none, so they stay single target (Double Shot's 2 arrows split between targets, so it does the same total damage either way). How many monsters a cast hits comes from each map's spawn points on the same platform within the skill's reach (75% alive), capped at its target count: an estimate shown as "hits ~2.4 per cast".
• Weapons: when the plan's character gets a better weapon, a step says where to get it: NPC shop and price (meowdb's shop list), crafting recipe (game files), quest reward, or monster drops (meowdb: player reports, else the old MapleSEA drop list it says Classic likely shares). The plan only picks weapons you can get at launch this way.
• Below level 10 you're a Beginner: basic attack with the Wooden Club, the Razor from level 5, and all AP in your future job's main stat, as meowdb's beginner guide recommends.
• Maple Island runs first in every mode: every island quest in order, island maps when a quest needs a higher level, then Shanks' ship to Lith Harbor at level 7+ (300 mesos, one way). meowdb: the island quests take you to about level 8. Untick "Still on Maple Island" if you've left.

Left out

• Quests needing items with no known drop source (NPC-made or unclear). They're listed under the plan, and quests that come after them in a chain are skipped too.
• Event, crafting, repeatable and Citizenship quests; Casey's Omok and Match Cards sets (very rare drops); Orbis, El Nath and Forgotten Hollow.
• Buying gear. 3rd job (not at launch): the plan keeps 2nd job up to the level-100 cap.

The score

• Each kill costs the monster's HP ÷ your damage, after hit chance, defense, level penalty and element, plus 1 second of walking and aiming.
• Score = map EXP ÷ total time, capped at what one player can kill per 7.56-second respawn. How many monsters a map keeps alive is its mob capacity from the game files (OSMS: worked out from map size, checked against in-game counts), often about half its spawn points.
• Maps need 8+ monsters; bosses are left out. Hit below 90% is flagged.
• Area attacks by default: Slash Blast, Arrow Bomb, Thunder Bolt, Poison Breath (or your Character Builder skill). Hits per cast come from each map's spawn points within the skill's reach, with the map's mob capacity alive: an estimate. Iron Arrow loses 20% per extra monster. Double Shot and Holy Arrow split a fixed number of arrows, so they count as single target. Thieves, 1st job Bowmen and 1st job Magicians have no area attack.
• Danger: one hit from the map's hardest hitter as a share of your Max HP: its touch against your W.DEF, or for Tauromacis and Taurospear (the only launch monsters with a magic attack) the magic attack against your M.DEF (meowdb's labels: under 10% Safe, 10–24% Caution, 25–49% Danger, 50%+ Lethal). Armor isn't counted, so it reads a little high. "Hits you" is the chance its attack lands against your avoid (meowdb's formula).
• To potions: portals to the nearest NPC selling potions (meowdb's shop list). A far refill eats into the real EXP/hr.
• Mesos/hr: monster meso drops at that kill speed. Per kill: floor(2.1 × monster level) + 3 mesos, ±10%, dropped on about 67% of kills (OSMS formulas page, fitted to in-game captures). With a Character Builder setup, "net" takes off your potions and ammo.
• Party: your share of the map plus the measured party bonus (+10/20/30% at 2/3/4+). Spawns grow 5% per extra player up to 100% at 6 (meowdb: not fully confirmed). Assumes equal players.

Set your real damage

• Copy the second row from your in-game stat window: Attack range (e.g. 43-200), Accuracy, Evasion, Max HP, Weapon Def. Magicians: Magic and INT instead of Attack.
• Basic attack (no skills) under Attack: 100% damage, one hit per swing at your weapon's speed, no MP. Bows and claws still use an arrow or star per attack.
• Empty boxes use the grey number in them: the Character Builder's default build for your class and level.
• Damage per second = your Attack range × that build's main skill, crit and weapon speed (named under the controls). Or build your character in the Character Builder and press "Use this in Where to train".
• Weak, low-level mobs win when you hit softly; tankier at-level mobs win once you hit hard.

Frugal mode

• For when mesos are tight: shows only maps where meso drops beat what you spend, fastest EXP first.
• Spending = potions for your skills and buffs plus ammo (the Character Builder's numbers if you sent them, else a default build for your class and level) and Red Potions for damage taken.
• Damage taken is an estimate. Monsters that hit you (default 1 in 4, your pick) sets how many of the monsters you kill get one swing at you first; each lands at its hit chance against your Evasion. Ranged classes can go lower, melee higher.
• Loot sold to NPCs counts in "net": every ETC item and potion players reported a monster dropping (meowdb), at NPC sell price, at 5% a kill each (default, cautious), 10% or 15%. Drop rates aren't in the game files, so this is an assumption. Ores, gems, equips and scrolls are too rare to count.
• Potions the map's monsters drop (Red, Orange, White, Blue, Elixir, Lemon) are listed under the map name.
• Maps rated Danger or Lethal are left out.

Left out

• Map layout and climbing, item drops and selling loot (except in Frugal mode), crowding.
• EXP/hr is an estimate. Use it to shortlist maps, then pick the one that feels best.

Columns

• Bonus: how much the quest multiplies the EXP of the kills it asks for. 3× means the quest triples what those kills were worth.
• Equals: the quest's EXP as kills of its target monster. If the items take fewer kills than that, the quest beats grinding it.
• Chain: click "Yes" to see the whole questline in order.
• Hover a quest name for its story, requirements and full rewards, or a reward icon for the item's stats.
• Must do / Recommended / Worth doing / Situational / Skip: what the community guides say about the reward (metaroad.gg, maplestory.quest, meowdb), with the reason under the name. "Valuable quests only" shows just those.

What's included

• Every quest you can do at launch, except Citizenship quests (they have their own tab).
• Orbis, El Nath and Forgotten Hollow quests are hidden until those areas open.
• Item-only quests show no Bonus, since drop rates aren't known yet.

The list

• Every monster you can meet at launch: field monsters, bosses, jump quests, KPQ and the 2nd job test maps. Orbis, El Nath and Forgotten Hollow monsters are left out.
• Search by monster, map or drop. Drops item shows only monsters players report dropping that item (pick from the list or type part of a name). Weak to keeps monsters the game files mark weak to that element (spells of it hit harder). Reset filters clears everything. Click a column to sort. Click a monster (here or anywhere on the site) to open its page.
• Best maps to farm it: every regular map it spawns on, ranked by how many of it you'd kill per hour at your class and level (estimate, same model as Where to train). The minimap shows where it spawns.
• EXP/100 HP = EXP per 100 HP of damage: higher is a more efficient kill.
• Stats, attacks, skills and spawns come straight from the launch game files.

Drops and mesos

• Drop tables aren't in the game files (the server decides them). Drops shown are what players report on meowdb; + is how many more players confirmed it than disputed it. Unconfirmed reports are shown faded.
• Mesos are the median of trusted meowdb player reports, times how often it drops mesos.
• Skill names the game files leave blank show as "Self buff #id".

The list

• Every item in the launch game files: equipment, use items, etc items, setup items and scrolls.
• Search by item name or by a monster that drops it. Filter by type, equipment slot and job. Click a column to sort.
• Type: Weapons, Armor (hats, tops, bottoms, overalls, shoes, gloves, shields, capes) and Accessories (earrings) narrow equipment; Slot then lists only that group's slots.
• Reset filters clears the search and puts every filter back to its default.
• Click an item (here, or any item icon or item name anywhere on the site) to open its page.
• Has a known source (on by default) hides items nothing is known to drop, sell, craft or give (event, cash and unused items are mostly these).
• Get it from keeps only items with that source, e.g. Monster drops = something is reported to drop it.
• Used for: Crafting component = at least one crafting recipe uses it; Quests ask for it = a launch quest wants it.
• Hide quest items (on by default) hides letters, proofs and other items that only exist for a quest: the game's quest-item ID range, plus items a quest hands you.

Item pages

• Stats, requirements, description and sell price come straight from the launch game files.
• Drop tables aren't in the game files. Drops are meowdb player reports (+ = net confirmations); a few weapons also list meowdb's old MapleSEA drop list, marked "likely".
• Shops are meowdb's NPC shop list. Recipes and quest rewards are from the game files.
• Players = the middle (median) price it sold for in player shops, from meso.watch (read off stream footage). "?" or "few sales" = under 5 sales seen, so rough. Prices move; check before selling.

Joining

• At level 12, sign up in Henesys (Arthur, Town Hall) or Kerning City (Roxy, Civic Center). The intro quest makes you a grade 1 Traveler.
• Each town has its own grades, quests and shop. Pick a town above to see it.

Earning contribution

• Daily board: meet each resident once, then their "Asking After" quest repeats daily. Contribution per daily goes up with your grade, not the quest.
• Weekly donation: bring 100 of one monster drop. Higher grades unlock bigger donations worth more.
• Story quests: one-time quests that open at grade 2 and 4.

Ranking up

• Each grade needs a minimum level and a total amount of contribution (see Grades).
• Grade 5 adds VIP residents to the daily board, worth much more EXP.

What you get

• Cheaper shops (5% → 25% off) and storage (95 → 50 mesos).
• Civic shop items, a resident's chair and 100% scrolls unlocked by grade.
• The town's earrings at grade 10.

Where the numbers come from

• Game files (launch, Oct 6): quests, EXP, mesos, contribution per quest and item rewards.
• OSMS Data Explorer (launch client): contribution needed for each grade.
• meowdb's Citizenship page: grade levels, discounts, storage fees, how to join, shop lists.
• meowdb says its info is from the second closed test. Housing, daily contribution limits and reactivation fees aren't confirmed yet.

The list

• Every item a launch quest (Citizenship included) or a crafting recipe asks for, so you don't vendor it by accident.
• Verdict: Keep all = nothing known drops or sells it, so you can't easily replace it. Keep N = what the one-time quests still want, minus what you have. Enough = you have what quests want; sell extras unless you craft. Repeatable = only weekly quests want it. If you craft = only recipes use it.
• Have: type how many you're holding; it's saved in this browser. Quests you tick done in the Path Planner stop counting.
• A quest rated Must do or Recommended is marked: keep its items first.
• Quest items an NPC won't buy (letters, quest-only drops) are left out: you can't vendor them anyway.

Where another comes from

• Drops: the monster a quest names, monsters players report and confirm on meowdb (votes shown), and meowdb's grind guide. Drop rates aren't known: the server decides them.
• Shop prices from meowdb's shop list, quest rewards and crafting recipes from the game files.
• NPC pays is the sell price. players ~ under it is the median player-shop sale price from meso.watch (where it has sales seen); players often pay more for quest and crafting items.

Thank you

• This tool exists because these people dug through the game files, tested in the Closed Online Tests and wrote it all up for free. Go visit their sites.
• Ranked by how much of this tool relies on them.

Rules this tool follows

• Every number comes from the game files or one of the sources below. Estimates are marked as estimates on the page.
• Unofficial fan tool. MapleStory is a trademark of NEXON; all game data and art belong to NEXON.

Getting started

• Six professions, each taught by a master NPC (cards below). From character level 10, finish the master's apprentice quest to learn it at craft Lv 1.
• Weaponcrafting's apprentice quest needs Smithing's apprentice quest done first, plus a Bronze and an Iron Ingot (Smithing).
• Professions feed each other: arrows need Smithing ingots, the Red Chair needs Tailoring cloth and Weaponcrafting screws. The "From scratch" column lists every part.

Leveling a profession

• Every craft costs mesos and gives craft EXP (columns below). Craft levels go 1 to 8 (the launch client's cap; the game files still list some Lv 9-10 recipes, hidden here).
• Each craft level also needs a character level: 5 × the craft level (Lv 2 at 10, Lv 8 at 40).
• Kits (weekly "in Need of Help" quests, craft Lv 2+): +10% craft EXP for 15 min.
• Catalysts (craft Lv 5 quests): use while crafting for a chance to change a weapon's or armor's bonus stats, or to turn a Lesser scroll into an Intermediate, Greater or Chaos one. The odds aren't in the game files.
• The six weekly help quests share one pool: 1 is offered per week.

Where the numbers come from

• Game files (launch, Oct 6): recipes, craft levels, mesos, craft EXP, quests, item stats.
• OSMS Data Explorer crafting tab: craft EXP per level and the character-level gate (read from the COT2 client).
• meowdb shop list: dye and helmet prices.
• Not in the files: drop rates, success rates, and where most ores and Fragment of Magic drop. A "Monster" source is meowdb's grind-maps guide (Leather, Stiff Feather, Animal Fur Bundle, Dragon Skin, Diamond Ore) or a guess from the item's name or description.
