Berserk

If this character has 5 or fewer Life Points remaining when it is activated, it gains +1 bonus to its Action Points and +1 ATTACK

FAQ, From Lewis Clarke on the Carnevale fan Facebook group:

Yes, it's possible (and a great idea) to activate Berserk with Frenzied, and remove it with Vampiric Attack. HOWEVER, Berserk only works when the character is ACTIVATED, not at any other time DURING their activation. So while you can get to 5 or fewer Life Points using Frenzied, it won't do anything until the following activation. No getting +1 Attack just for that action!
