Patching our xaurip skirmisher stunlock would be a nice start.
I'm still bitter about POTD having.a xaurip at the start of the bridge so you get instantly jumped and potentially killed if you go there solo
Amusingly, it used to have two uses, and Obsidian couldn't stand for that:
It was worth a lot of money if you sold it to Heodan, and you could later enchant it which would override the Terrible quality. Now it's worth hardly anything and you can't fix the quality.
Re: the Disappointer-- I didn't find it in it's first location in the game, but
when I found it at the second spot, well... I think that might've been the best joke in the game.
