A good combination to inflict a Devasting Physical atack on your enemy is to use:
1-Predator Form 2-Animalism 3-Enrage
(the Enrage u can only use it 2 turns the turn u invoque it and when u atack)
this combination will surely strike a devasting atack more than 3000 of damange well . . . . depending of your strengh if u havew more streng more damange
newer skills may last longer and give better stats, i thought things like that would be easy to relize, its kinda off topic since they wouldent be bio abilitys :P
