Cerberus (demon)

Cerberus is a demon found in Iris and the Giant.

"One of the heads of the terrible Cerberus. The legends say its heads grow back after a while. I won't give them the chance!"

Location
Cerberus can be found on Floor 8 in Path of the Giant, and Floors 15 in Path of the Ferryman (Easy and Classic difficulty) or Floor 13 (Nightmare difficulty).

Strategy
The Cerberus will always appear in a group of 3 (one in each column), and will have 2 Armor each. You must defeat them all in a single turn, otherwise they will revive with their armor restored.

Since they will hit harder than most enemies, you should keep them in the second or third and break their Armor using ranged Cards, keeping Amphora, Crystals or weaker enemies in front. Once their Armor has been destroyed, you can defeat them with an Axe, Thunder or any chainable cards like Sword.
