Master_64: After 5 minutes of fighting or after losing 150HP, Latent power will give you: (+1): +50% affinity, 30% less stamina usage when rolling. (+2): +70% affinity, 50% less stamina useage when rolling. I'm not 100% sure these informations are right. I simply used this ability since it was the only abillity i could fit into my Focus,Normal Up,Challenger+2,AuL set.
