Binky!

My paladin finally got 4 others to tag along to Scholomance and kill a bunch of ghosts ... and finally got his uber-mount.

The quest itself if pretty cool. To "kill" the ghosts, you have to pass judgement (using the spell, Judgement) on them. But you have to figure out which judgement works during each wave. So, for example, Judgement of Light works only against Shadowy Spirits, or Judgement of Wisdom against Banal Spirits. One of my party observed that it was like a SAT English test ... figure out the antonym of the word in the name of the spirit and then figure out what spell best matches it.

PS: For those of you wondering why "Binky" - in Pratchett's Discworld, Death came astride Binky.
