This is easily one of my favorite pieces. Between Weirdworld and that Crystal Shell defense this guy is hard to hit!

[E] Has the ;Indomitable; defense symbol printed on his base instead of ;Shield; "

he's not indom

That actually means he is indom, they just misprinted his base.

Thanks for correcting me on this.

This guy was a very solid melee fighter in our last game. Charges in, indom, re-rolls his attack or BCF, and last but not least has a damage reducing power that can't be outwitted and doesn't care about people perplexing their damage up, since that won't work thanks to his trait. He was surrounded, but since nobody had penetrating damage or rolled exactly 18 or high enough (nor could perplex up their attack!), he lasted forever before eventually a guy with Poison managed to hurt him little by little out of his defense special.
