Why the hell is his Potion list non-removable? I don't want to run through the entire game (or at least as long as it takes me to find all this stuff) with an Inventory slot permanently taken up by a note, especially when I've already got a duplicate list in my Journal. And the Journal is even better, since I can edit it to check off what I've already given him.
On another note, I sure hope all these Potions have actually been added to the game, and don't depend on things like Improved Kangaxx, the Alchemy HLA, and Tutu. I also hope they weren't placed in Gorch's inventory, since I killed him before I even saw Jadarath.
Very interesting quest, and personality, though.
