Traps seem to have a couple of oddities that are inconsistent with most other skills in the game, the first one I think you are aware of so I am unsure of if its a bug, it is an inconsistency so I'll state it, but the 2nd one almost assuredly seems like a bug to me as well.
1) Traps appear to inflict targets regardless of if the attack hits or not, through Body of Isesip/Glancing/Full Dodge
2) Traps appear to be able to roll infliction checks against corpses:
It seems like traps just don't have infliction tied to the actual hit itself, which is perfectly understandable but I figured I'd throw this up anyway in case this isn't intended.
