There is a new area for undead hunting currently in premium preview for one week. I thought it might interest you to know that they are designed to fit in the gap between dark fiends and dark spirits, and although they can be dangerous, protection from evil will give you an advantage when facing them.
Thank you all for your responses on my earlier post. I will probably make the spell a slot, and am still playing with the numbers in terms of adjusting teaching and lore. Although many of your suggestions were excellent, some don't quite grasp how the current requirements work, and I am not allowed to discuss the details of it, but due to the mechanics and way it does work, some ideas won't be practical to do. Again, my intent is not to make it any harder than it is, or greatly easier, but to try to provide an alternative. I promise to warn you if/when it changes.
Still tinkering with spells and commune stuff, still working on Surlaenis homes, still the to do list grows longer despite the things that get crossed off. <grin>
