I know the Priest Tree was probably intended to be there more as a supplement to the other classes, rather than a class to itself. Having played using the other classes, it's been a lot of fun trying to make it with just those skills. I welcome the challenge. It just leaves you feeling cheated, with the XP gains all over the place, influenced by Charm or not.
The Sek-hat Troll is the one I was referring to, but it's not just him. This is happening all over the valley.
