[@DracoLunaris]: Hm...
Well, if the mana issue is resolved and only really for personal reference, then sure, that's fine.
With regards to MP drops... I think that's an interesting risk-reward, but could be dangerous. Up to you which to pick, though my preference is towards the latter.
As for the dash (blink)? I'd rather nerf it since it seems quite spammable in the video example, and phasing in and out of reality where you can dance around hits like that is rather tough to work around. Would rather it be a proper dash instead.
