I have noted that the trace damage that can be dealt with the grappling plunger still seems to be treated as non-plunger damage by The Clog. I noted that the grappling plunger still did a notable amount of damage to the clog, but it was still certainly playing the non-plunger voicelines.
This is an incredibly impactful and meaningful inconsistency that will be surely noticed by all if it is not remedied very quickly.
