UNIQUE – BLACKOUT: You Disabled Ward icon disable surrounding wards, as well as Exposed icon exposing stealthed wards and Noxious Trap traps. The effects linger for 2 seconds after you walk away.

I bet most of you didnt even know it had a slow because you instantly die anyway, or the fact that with dusbklade you almost always know if area is warded, OR THE FACT THAT IT HAS NO FKING COOLDOWN

even if it had cooldown it would be OP item Idk what else to say

I mean either ghostblade is underpowered or duskblade is overpowerd And we all know what the truth is
