ReferenceMT2Calc is the most complete fan-made calculator site for Monster Train 2 — the roguelike deckbuilder by Big Fan Games (Devolver Digital, 2025). Use it to theory-craft builds before a run, work out the exact Pyregel stacks needed to one-shot a boss, figure out whether your Pyre survives a Covenant 20 run, or just look up what a keyword does mid-session.

Floor damage simulator
Model your full three-floor setup. Each floor shows unit attack, copies, and keyword modifiers. Total DPS updates live.
Multistrike calculator
Multistrike causes a unit to attack multiple times. Each stack adds one extra hit. The first stack doubles damage — but each additional stack yields diminishing returns.
Pyregel damage calculator
Pyregel is a Pyreborne debuff that increases every instance of damage taken by its stack count — permanently for the duration of combat. Stack it, then burst with multi-hit spells.
Pyre HP breakpoints
Model how much Pyre HP you'll have after each wave. Know exactly which fights you can afford to take damage in — and which ones will kill your run.
Clan synergy planner
Pick your primary and allied clan, set your target playstyle, and see how well they mesh — with keyword overlap analysis and strategic tips.
Status effect calculator
Model how buffs and debuffs interact on a unit. Enter base stats then add status stacks to see net effective attack, HP, and incoming damage.
Keyword glossary
Every status effect, keyword, and game mechanic explained with exact interaction rules — from Sweep + Trample combos to Explosive overflow.
