Brand new to the EE games and these forums, so I apologize if I am unaware of something obvious here. I searched these forums, the release notes, Reddit, and elsewhere, but couldn't find anything.
When I have played the original BG games in the past, I played with minimal reloads, and would move on if a character was permanently killed (portrait removed from sidebar, such as when petrified, disintegrated, "chunked", etc.). However, after having started in BG:EE I became suspicious that this feature has been removed. With some casual testing, I've noticed that it is seemingly impossible for this situation to occur in regular combat, whereas I believe in the original it could be triggered by having a blow reduce your character to -10 HP or lower. With ogres and flesh golems, I've noticed that having Xzan at 1 HP receive critical hits from these foes will not cause permanent death - with expanded battle information turned on, I can see that he is seemingly blocked from reaching -10HP, with any such damage that would have been received being negated by an out-of-the-blue and behind-the-scenes increase in damage resistance.
I was playing on Insane, but this occurs when I lower the difficulty to Core Rules as well. Looking at the Baldur.lua and in-game configuration options, I don't see any indication of a way to re-enable this feature. Without this "option", I find it very difficult to role-play choices in the game where the PC would abandon long-time party members in exchange for unfamiliar NPCs encountered very late in the game, whereas before these characters would neatly fill in slots used by characters that met untimely fates.
Does anyone have any information about this?
