Yasha-7HS

The hitbox is very high. It goes from your face to where you're pointing at and the hitbox itself is 2 meters high. This is why you can't get through open doors unless you crouch. This also counts Vazarin's guardian shell as an object and causes the ability to be literally useless.

Mag does the same thing with breach surge. This isn't Kullervo being uniquely powerful, it's just breach surge having an interaction with an ability that multiplies and redirects damage.

Sick I would highly recommend removing the cap on Kullervo's Overguard. It wouldn't be all he needs to stop one shots in the latter end of SP Circuit, but it would be a step in the right direction. Wrathful Advance has issues passing through doors and cannot teleport through Vazarin's Aegis.
