What Nemesis does
Monster, Character, Stage, and Module sheets in one project. Inline editing, drag-to-reorder, and JSON export — no external spreadsheet needed.
Select any entities across sheets and compare their stats side by side. Stat Balance bars highlight outliers the moment you add a row.
Define balance metrics with your own formulas — cross-sheet references like ATK / (target.DEF + 1), level keywords, and per-rule colors.
Five analysis modes: Full Balance, Character, Monster, Stage, and Difficulty Prediction. Claude returns a scored breakdown with concrete fixes.
Write ATK + (level - 1) * atk_per_lv once. Every chart and AI report automatically uses the scaled value for that entity's level.
Attach gear and upgrades as Module sheets. Run a single AI analysis and get a side-by-side baseline vs. with-modules breakdown.
How it works
01
Build your game's entity database in multi-sheet tabs. Enter monster stats, character progressions, stage compositions, and modules in a spreadsheet-style editor.
02
Select entities, define Game Rules formulas, and see Stat Balance charts update instantly. Spot outliers and scaling gaps before players do.
03
Choose an analysis mode, hit Run, and receive a scored breakdown from Claude — issues, strengths, and concrete fixes in plain English.
