[Snake]

I agree with everything listed, it's not OP and it opens a new 'branch' for a Ghost build, pretty thematic for the skill's description aswell to freeze people in place out of fear for the cost of the 'low level curse' named Claret Call.
Personally, I'd love to see some actual 'fearsome' ghosts than the majority of desperate berserkers running around and flailing Ether Invitation casually. (Because that's the way most people play Ghost as, yeah, boo.)
