Shifting trauma: It's currently by design that this doesn't count as a kill for you. You may or may not be able to talk Santa Zulg into changing that.

Black wineskin: FNCR.

Owaza: Yeah, mobs can potentially flee midway. They aren't subject to the same lag rules that PCs are.

Morosa demons: Work that way by design.

Mob that duos: Is working fine; your understand of how duo works is imperfect.

Long range devils: Yep, by design.

Fend: Isn't quite as good as you think, but has still been downgraded.

Trap affect stacking: Doesn't seem like it should be possible from a glance at the code, so a log would be appreciated.

Stone of frost and conglaciation: Fixed.

Adrenal surge: Yes, by design.

Swing: Working correctly; it doesn't work exactly the way you think it does.

Boneshatter weirdness: FNCR.

Potions: Keywords that aren't what you want them to be are not a bug.

Silence, cabalguards, and applicants: FNCR.

Pummel special: Still exists, but if for some reason you're not very good at pummeling or not very good at pummeling a certain target you might never see it, and it's rare in the best of times.

Spamming vs. eagle: Not sure what your problem is, but I know that other people can make what you're trying to do work.

Area spells: Yes, they can hit your groupmates in some kinds of rooms, including the one you were in.

Shove: I'm going to call that one by design for now.

Bloodlust: Is working correctly; you're still affected by it, you just can't tell that you are because of another one of your affects.

Nexus priests: Yep, you're the catcher.

Balance of the sisters + double whirl edge: Fixed.
