Right, so, here's what I got from that.

The poison is a relatively normal one, and I assume that it is designed to do such things against humans. Demon limbs are solid, with raw demonic energy holding them together; no veins or the like for poison to flow through. That makes the poison unable to really go anywhere, and since Zargon, in addition to having control over every element of his form, is more powerful than a normal demon would be, the poison would be centrally located, and with a little concentration can be expelled without too much effort.

Basically, it would feel like a stinging cut to him, and since it is designed for paralysis, the limb in question would be temporarily disabled. I didn't see much on how acidic the poison is, so I assume it is a little bit.

Barbarian was used in the context of a demon's viewpoint; so that would be hulking blobs of twisted animal, human, whatever that was turned into a demon-esque soldier. Lowest in the demonic hierarchy.

@The Fated Fallen, your turn. Save yourself, gnome.

Psst psst, who's next? :p
