[@Rune_Alchemist] I have problems with illusory forest, as that means id have to tolerate a table flip of sorts should you go rogue and screw with tour teammates. 
Rather than a large area can it just be an influence over a single target that lets you manipulate what they see. Illusory foes can stay but will do no damage.

As for the undead knight, the bonuses given by blessing of the fae to their overall stats would make them unstoppable. The armor piercing cannot be allowed for reasons involving ease of victory over my established "villains" of the rp later. 
I may have also overlooked this but does she hold her head at all times? Or can she only use one of her items at a time?
