Hello,
Today I've beaten BG1:EE with SCS (a mix of Improved and Tactical settings, all tactical challenges except Improved Kobolds enabled), and I enjoyed it much better than the original. There are a couple of things that bother me a little, though:
First, Aec'Letec does not seem to be fully affected by the Improved Fiends component. I didn't see her teleporting around the battlefield, and I'm pretty certain that my difficulty for this component was set to Tactical. It was still a fun battle, but the cultist fight in the previous room posed a greater challenge. On that note, the Demon Knight wasn't teleporting around, either. Is this behavior intended?
My second piece of feedback concerns the chess battle. I had the greatest number of reloads in that place, but there were two scenarios for opponent behavior. If I entered the battle normally, all opposing pieces would instantly aggro, rush forward (within rules, but that's enough to sow chaos and despair) and try to kill my king no matter what. But if I used a potion of invisibility on my main character before the battle began (i.e. while fighting the last elemental warden), the enemies on the chessboard remained dormant, unless provoked according to usual rules (or my main character became visible again). This makes the fight significantly easier for the price of never using your king (to me, it was still a lot of fun). Do both of those scenarios work as intended?
