Im also on her stage 3 character tower and theres no more brutality to unlock yet i dont have 2 of them still

Every single character tower has a brutality at stage 2 and stage 4. There's also 1 Jade brutality in Kombat League rewards.

Agh i thought was only 3 stages.also any idea about the brutality not working?

Unlocked now problem solved.requirements were in moves list finishers even thou i hadn't unlocked it.hence why i was confused .it wouldnt work as u norm dont see the move in moves list till you unlock said finisher that brutality.
