There's a non-journal encounter with a Nord, Harryk the Rude, standing on the road west of Teyn. He offers you to buy a barrel of pickled fish for 50 drakes. If you do, he puts the barrel into your inventory implemented as a potion with 4 effects (one of them is drain personality 20) that last 900 seconds. The whole gimmik of the encounter is how Harryk the Rude speaks to you in a rude way (he uses a word guarsh*t which is too much, imo), and that the fish makes you stink (=drain personality).

The barrel-potion idea feels awkward. So, my suggestion is to make the barrel be a normal container that remains in place, and you can simply take the fish out (changed to dried slaughterfish instead of pickled so as to not invent a new ingredient). And I suggest to change that one word to make it less edgy.
