Trying IWD with the Heart of Winter from the "3 in 1 Boxset"
v1.3.062915
Patched to v1.06
The HoW is v1.40 (at least that's what the Readme says).

I'm playing BG2 for the first time on PC, having played about 1/2 of
it for the Mac a few years back. I thought I remembered that you could
set an option for ally spells to not damage your other allies, but I
don't see that option any here. Am I just mistaken in this memory?
