If you are using a version older than 6.2 you may be interested in this add-on: Link. Install it on top of Item Randomiser.
It fixes the following two issues:
- Glaicus will now correctly hand over any flail heads he may possess if you charm/dominate him.
- Fixed a vanilla-game BG2 bug where creatures could stand around like idiots because they were trying to drink a non-potion item.
