I seem to be having an odd issue that I do not see a recent thread about. The Cauterizing Blaze (T8) power in the Fiery Aura Sentinel secondary doesn't seem to be doing anything. No green numbers coming off my head (other heals do) no +Regen noted in the combat attributes tab, nothing. I was testing it mostly by using falling damage, no appreciable effect on or off. Anyone else notice this? Is there some sort of conflict that is causing this to occur? Fuegocito
