So, if you start your character as a Lupine, equip War Cry, then switch to Vampire, you get to keep War Cry. I'm not sure if this is intended or a bug.

I reported a bug a long time ago where if you equipped Poison Bite and used an ink to go Vampire, you would keep it in your skill pool. It might a similar problem.

This should be corrected. But it'll also correct itself automatically when you load your character currently (or should).
