[Perdition]

If it only applies to basic attack then the item remains worthless so it should have some interaction with evasion! too even if that means tweaking what it does. Also, the argument of multi proc autohits guaranteeing that the fangfare user gets to auto teleport behind you is no different than certain setups punishing those kinds of moves more than single hit ones already. Things like Bellplate and Fang Face shield punish multi hit attacks oppressively and are not near as bad for single shots. Mirrored is cancerous against multi hits far more than it is for single hits. Divine Rain, Thousand Stab and other things are also not things you NEED to use. If you're against a Fangfare user, nothing is forcing you to use those skills.

On top of that, it's still a str based dagger at the end of the day, so it's already at an additional disadvantage. Furthermore on top of that, other str based daggers in the form of the Tsukikage set can straight up teleport you behind people from a decent range. You trade a 24% chance to do so from any range to being guaranteed to do so at a generous range. A 24% chance to dodge behind someone is far from busted when you look beyond a couple of specific skills.
