Grah-Hoth still exists, he’s just in some sort of Hell. He’ll be back…(not in this game though)

When I played through it a few months ago my strategy was to use Blink and get my spell casters with their backs against the North wall so that fewer enemies could surround them and spells that used cone attacks were more effective.

In Exile I could beat that fight without taking any damage as long as I had 2 people who could cast high level mage spells (you had 6 characters in that one) and alot of energy potions, using this game-breaking “protection” spell you found in the Ogre’s cave. It was too costly to take you through an entire dungeon, but for one big fight it was totally overpowered. There wasn’t a dungeon to traverse, you just walked right in and the big fight was right at the entrance. Once you killed Grah-Hoth the other demons gave up. Once you knew how the fight worked, it was easy.
