I didn't grind through so many hours only to lose all my items just when the story was picking up. I led him back to Kuldahar (cause her mages were still alive), had him revive all my party members, so i could go back to Dragon's Eye and retrieve the items that my party members had dropped. Only Gloin, my dwarven fighter/thief, managed to live. Eventually, through a right combination of spells, good timing, and favourable RNG, i managed to slay her, but she and her yuan-ti mages absolutely slaughtered my party. I didn't want to lower difficulty, because i swore to myself at the beginning of my plathrough i wouldn't.
She was very tough, and i couldn't beat her. I faced the first serious boss in the game, the goddess Yxounomil (or something like that). So i was playing Icewind Dale Enhanced Edition on Core Rules difficulty, for the first time ever. Hey i know it isn't about an Obsidian game, but this is the only forum i could think of that i already had an account on, and which was populated by nerds like me.
