Damage Matchup (Preview): every participant is both an attacker and a defender. Enter 2 to 8 participants; the table shows what each one's attacks do to each of the others in one round, after that defender's Con, armor class and protection spells (the same calculator as the Damage Calculator).
An attack's damage is the raw hit before the defender's reductions. Leave hit chance empty and, when those two fought in the logged Algoron Gladiator League fights, the measured hit rate of that pair is used (the logged damage is a severity-band estimate of what that defender took, so it is shown beside the cell, never used as the raw hit). With neither, the cell is marked incomplete rather than guessed. Dodge, parry, shield block, resist/vulnerability, dragonskin procs and spell damage are not modelled.
