Planar Vortex - New Ability: Whenever the Riftstalker Plane Shifts, they gain Planar Vortex which lasts for 4 seconds. Deals 50% of your weapon damage every second to surrounding enemies and generates a large amount of threat. Effect can only be triggered when the Riftstalker is in Guardian Phase.
Why limit this to Guardian Phase? Enabling it for Stalker Phase would give the 20RS builds the extra help it needs to be on par with Sabdancer in a raid setting
Guardian Phase: Generates a large amount of threat.
Stalker Phase: Planar Vortex is affected by your AP in some way.
