COMBO calculator

Pick a trap and its level, how many traps go off in the same turn (COMBO) and for how many turns in a row traps have caught the same enemy (CHAIN). It shows the damage of every hit and the total, assuming the same trap used on one enemy.

How it is calculated

This is the same formula as the game's damage code (game_core). Every number is generated from the game data.

damage = round( trap power x COMBO multiplier x CHAIN multiplier ) - enemy armor
(if the result is below the minimum damage, the minimum damage is used)

• COMBO multiplier: set by which trap of the turn this is (1st, 2nd, ...). From the last row of the table on, the multiplier stays the same.
• CHAIN multiplier: set by how many turns in a row traps have caught that enemy. From the last row of the table on, it stays the same. COMBO and CHAIN are both multiplied in.
• Rounding: power x COMBO x CHAIN is computed first and rounded once (0.5 rounds up). Then the armor is subtracted, and anything below the minimum damage (1) becomes the minimum damage. A trap with several damage effects does this for each effect and adds them.
• Armor: the amount the Armored trait subtracts grows on deeper floors. Enter the amount subtracted per hit directly (0 = no armor).
• Not included: element reactions (oil + fire, wet + lightning, frozen + physical...), armor skills (trap damage up, COMBO multiplier up...), damage reduction from shields and helmets, and special boss handling.
