I played this initially on my normal run, went fine, then on 2nd run through game, on Tactician this time, it was going OK, but Gale dropped a fireball near her - not realizing she would be affected - since Gale can sculpt evocation spells and this should allow you to select who is excluded - but clearly that is not implemented correctly. She was immediately unconscious *boom*, end of fight (that I had almost won)...annoying. I was going to redo it, but was curious to see how it panned out with her being kidnapped, so just carried on from that point. Everyone at the Inn died and turned undead *everyone* including Dammon, so no more fixes for Karlach's heart. Afte rthe fight inside, I then had to deal with all the former harpers etc outside too. That only left Jaheira to help when I attacked Ketheric, which was quite a different experience.
Anyway, since you are protecting Isobel, it makes sense that you should be able to apply any boost you do to allies. And sculpt spell should work in this case. This seems more like an oversight of the devs (one of many, to add to their list -esp around spells/rules implementations). They should really have marked her as an ally...
