Just curious...can this kind of mechanics that IPA uses be applied to a custom race (if one goes for the robot / Cyborg thing)

Yep, you just give them an ability that has the IPA base effects as detailed in the readme and it should work. It works as an ability added to creatures as well.

It seems that the Hellfire helm isn't triggering the head armor for me. Is this a known bug, or is it just my end?

EDIT: I found the source of the bug, the Hellfire helmet is missing the Hair biped slot, and apparently your conditions for head DT work on that.

I know I might be a little late on the punch line here, but thanks for this one. Your mods are always Awesome, from this to Robco Certified, to Wasteland Whisperer... This just makes it even better. :celebration:
