Spike as a witch/wizard

I wonder if there are any stories where Spike can do magic (is a witch ) or has any powers beyond that of normal vampires

I have one that just barely fits that criteria: in "Knowing and Watching" Spike is Buffy's watcher in an alternate world to which they've been sent. He uses a teeny bit of magic during the course of the story, but isn't really a sorcerer or witch, just a watcher with some knowledge of the magic he may need to use from time to time.

In "To Hell and Back" by Palerider, Spike and Buffy both receive a special ability that can be used together.
