Phases

Combat in AutoRaid is divided into 5 phases with Heroes only having access to abilities from that phase or lower. So for example at phases two a Hero can use it's basic attack, phase 1 abilities and phase 2 abilities. But not phase 3 abilities. Phases 1 to 4 are 30 seconds each and Phase 5 which is the final phase takes 1 minute. By the end of Phase 5 you must have killed all of the enemies in the dungeon or you will be defeated.

Abilities get more powerful as the phases progress with phase 5 abilities designed to have a major impact on the battle.
