Grimm seems kind of OP...

I mean, he can control souls, make zombies, control shadows (basically doing what Assallya does), is really good with a scythe, and can resurrect people. I kind of feel like he needs more weaknesses than mild nausea to a certain stone when he's within 15 metres of it...

I mean, with that kind of power I'd give him a severe weakness to sunlight and feel like he was on fire whenever he entered within a mile radius of delphite (I assume it's quite rare- if not, then lower the radius accordingly)...I mean, even making it so that he always looks horrific all the time would be a good start...
