Mechanics
Super and ultra classes
A character can hold one ultra class; its abilities cannot be mixed with another class's abilities, and its holder can no longer talk to other ultra-class trainers. [1]
Details
Kharvos can reset an ultra class through a trade; the trade cost is unconfirmed. [2]
Equipping another class's ability makes a super-class hybrid, which forfeits the pure class's stat buff. [3]
