He should have Super Senses, because if he doesn't make the roll, he takes full damage, which suits him. SS doesn't fit, but a 3 or 4 damage for giant fists, etc ONLY on the first click, would be good, then 2 damage with Poison. All my opinion, of course.
The greatest commandment is to love the Lord with all your heart, soul, mind, and strength. The second is to love your neighbor as yourself.
