MapleStory Legion Planner
List character levels, see your union total and weekly coin income — plan which character to level next.
Union level = your roster's sum
MapleStory's Legion (Union) system converts your whole character roster into one pool: every eligible character (level 60+, with break points for bigger tiers) contributes its level toward the total union level that buys board space and effect slots. The planner sums your entered levels to show where the union stands, how far you are from the target, and which single character's next 10 levels move the needle most — usually the weakest one crossing a tier break.
Alt levelling = the real progression
Union planning in MapleStory is really alt management: a fresh character from 60 to 120 often costs less total time than pushing a single main to 250 past the soft walls, while vacuuming up a dozen tier-break leaps for the union. The planner shows per-character level shares, so you can spot the cheap levels (new alts at break points) versus the expensive ones (late-game-plateau mains).
Coins and the weekly grind
Union coin income scales with union level/per-piece grid, and coins fund the daily attack/XP/crit purchases that help your entire roster at once. Values per version vary, so the planner keeps coin numbers approximate and honest — the actionable output is the union level plan, and the coin estimate is a running reminder that the board pays weekly on the roster you already built.
Frequently asked questions
How is union level calculated?
Commonly: the sum of your eligible characters' levels (level 60+ typically counts, with tier break points). The planner sums what you enter; verify against the in-game Legion screen per version.
Which character should I level next?
Usually a fresh alt crossing a tier break — more union per hour than pushing an already-high main past a soft wall. The planner shows each character's planning weight.
What do legion coins buy?
Permanent-ish account-wide buff purchases (attack, XP, crit, drop) from the Legion Shop, refreshed periodically — pass-level income grows as your roster grows.
Is this affiliated with Nexon?
No. MMOKB is a fan tool and not affiliated with Nexon. Union mechanics are version-dependent — verify against your region's current patch.
