I've found a couple of bugs in Blight Caster, not sure where to report these anymore. :P
1. The Blighted Wolf wild shape is not applying natural weapon feats, and appears to not consider itself a natural weapon for spells like Align Fang.
2. It is possible to have two forms as a Blight Caster at the same time. Though one of them must be a wolf form. Take wolf form, mount a horse, change to bee, thorn, or the other wolf form. The second form will control attack animations, but the first form will show movement. Both will apply their effect and appear in the buff bar. It persists through login and zone changes. It can be fixed by going into the original wolf form.
