I finally got done the game. The problems have been signifigantly reduced, though there are still some.
Paladin Cork - he still dies. Again I gave up trying to save him, even coming out of the castle and fighting with my whole party right behind him. He dies in two hits.
Paladin Garret - I decided to not save him this time and let him get killed off. The end result is my party wasn't able to get the source collars removed. My main character got the collar removed after the fight arena underneath Fort Joy.
Magister Alexander is entirely too OP. She hits you with a nasty stun spell and your entire party is stunned and killed off without getting a hit. I discovered a nice glitch to get around it. While she's talking with the main character, I was able to get all my other characters in place to have the fight. It was easy to teleport my main char out of the stun cloud. Final battle wasn't win-able without abusing this bug.
I'm also deeply saddened that the giant voidworm spawns after all those magisters are killed at the end. I found it to be really awesome when the voidworm spawned in the middle of the fight. That kind of chaos made the fight really enjoyable.
