Boss
Map room
The deadliest foe in the area.
Defeating them will let you proceed to the next Act.
Defeating them will let you proceed to the next Act.
The boss room is the last floor of each act, a single node every path leads to.
Rolled early: which boss waits is set when the run is generated and shown on the boss icon from the first floor.
Own tables: bosses use their own HP and damage numbers, jumping at Ascension 8 and 9, and usually add phases or summons normal enemies lack.
Win: clears the act, gold from the encounter's range, a possible potion and a card reward with three Rare options, then the next act's Ancient heals you.
Relics: bosses drop none on their own; Lava Rock makes the Act 1 boss drop 2.
Ascension 10: the final act has two boss rooms back to back.
