Im going to steal some of the "facless one's" arms to make it more mutated.
Can you do what gameman said, but make his a arms hydra brown and his suit cracked?
you may want to mention that its somewere in the middle of your code, else newbs may try and look up top were the object id's are placed.
Edit:
how would we set the damage in a range (say 1 - 100)? i belive adding that would make your trigger more usefull.
