Questions, answered
Is combat automatic?
The squad fights automatically when a wave starts. You intervene with Hellfire and Rage and make card and treasure choices between waves.
What happens when I choose the same demon?
Choosing the same demon through a between-wave card can raise its combat rank. Higher ranks unlock awakenings and support role synergies.
Can I practice without spending resources?
Formation practice uses no energy. After daily raid attempts are spent, unlocked bosses can still be practiced for free without rewards.
Must I pay to unlock demons and chapters?
The store description says all demons and chapters can be earned through play. The game contains ads and in-app purchases, and summon and equipment-chest probabilities are shown in-game.
