This build works great in unison with other casters laying down crippling spells on the exit point or archers sending volleys into enemies while they helplessly get pushed through the portal and grounded.
Teleporting itself also works well for some battlefield control with bottlenecking enemies or sending them off a distant away to get some breathing room. Both great for utility application and damaging groups of enemies and sending them away from the caster for defensive purposes.
