Blood Rush

Blood Rush is a Blood and Bone skill in Diablo III.

In-game
The Necromancer sheds their mortal flesh and reappears up to 50 yards away, passing through most obstacles and clearing Immobilize effects.

Functionally it is similar to other relocation skills, like or Dashing Strike. However, unlike the said skills, it does not provide damage immunity while the Necromancer is moving.

The Necromancer can phase through enemies and most obstacles (even solid walls) this way, but cannot move through closed doors.
