They weathered themselves through intense training to withstand ailments and injuries
Cosmics armour break cos they’re powerfulMystics nullify buffs cos of their spellsTechs power burn using their tech equipments..Etc…So how do Skills make debuffs disappear? Anyone know?
Then how do you think science champions petrify? They inject serum into the opponents while fighting to slow their regen and power gain or make them slow?

you’ve never cut yourself and just willed the bleeding away
Personally I'd like to see them mix it up Why not a mutant that shrugs debuffs or a tech that nullifies, etc.
