About this converter
Devil Room deals charge red heart containers with soul fallback. Standard 1-heart deals cost 1 red container, covering Pentagram, The Mark and Book of Belial. Standard 2-heart deals cost 2 red containers, covering Brimstone, Moms Knife, Spirit of the Night, The Pact, Deaths Touch, Lord of the Pit and Abaddon. With zero red containers both tiers cost a flat 3 soul or black hearts total, not 3 each. Repentance swaps some soul rewards to black hearts with costs unchanged. R Key is the exception at 2 red or 1 red plus 2 soul or 3 soul, noted apart from standard rows.
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 Brimstone against Pentagram to see the 2 to 1 deal gap. 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.
Two heart equals 3 soul each is wrong and flat 3 total is used with the correction noted. Angel Shop coin prices like 30 cents use a separate shop table. Repentance occasional soul prices with reds held are edge cases outside standard rows. Omitted: Krampus drops, which use boss tables, not deal math.
