Thrasher said:I had control of the character, there's just never a move option during combat. I think she got permanently stuck by a Giant Mantis or something. Even emptied her inventory, but since her movement was shown as 6, I think it was bugged. Tried remove curse, restoration, dispel, etc to no avail.
Check the "effects" or something tab in spellcasting/memorizing submenu, it shows which buffs and ailments affect party members.
Edit: it's encamp/magic/display.
For trolls, you can buy a lot of flaming oil flasks and use those to finish them.
