Mega Satan totals 5000 from 3000 plus 2000, not 6000, with 600 HP hands respawning every 30 seconds. Hush pays 6666 with armor scaling plus a 500 Skinless add.

How to use it
Pick two entries and a unit in the top row. The three boxes below stay linked. Change any box and the other two update. Try Delirium against Monstro to see the 10000 to 250 span. The result line prints the equality plus the per unit ratio. Click a table row to load that entry as Entry A with amount 1.
Larry totals multiply 22 by live segments, noted in context. Mega Satan hand kills add 100 damage to the head per kill. Hush armor scaling reduces late damage in game but base sorts here. Afterbirth and Repentance bosses ride the same Rebirth base table with DLC tags. Omitted: miniboss HP, which uses a separate enemy table.
