About this converter
Slay the Spire boss health runs 140 to 750 base. Slime Boss opens at 140, Guardian at 240, Hexaghost and Donu and Deca at 250, Collector at 282, Awakened One and Bronze Automaton at 300, Champ at 420, Time Eater at 456 and Corrupt Heart at 750. That makes the Heart equal over five Slime Bosses. Ascension 9 plus lifts several rows off page, so rows pin base values.
How to use it
Pick two bosses and a unit in the top row, for example Corrupt Heart and Slime Boss. The three boxes below stay linked. Change any box and the other two update. One box holds a count of the first health pool, one holds the matching count of the second, one holds total HP. Try 1 Time Eater against Guardians.
Heart caps damage at 300 per turn, so three rounds minimum clear it. Donu and Deca fight as a pair totaling 500 off page detail. Elites like Gremlin Nob sit out since rows pin bosses only. Ascension lifts several rows off page, so rows pin base values. Minions like Louse packs sit out since rows pin bosses. Elites sit out for the same reason across acts.
