Ape

Token Upgrade
If upgraded with a Pet Token, Ape will use his first action in dungeons to transform into super Ape. The transformation will last for class level / 5 actions, and gives a class level% boost to all stats and Ape will hit twice. This means at class level 100, Ape would have a 100% boost to all stats for 20 actions. This only works once per room.

Recomendation
Ape could be Unlocked during an UPC, while pets run item camps and level up, since the Challenge require no rebirths for a long time
