Eldritch Reach

Caster must reach out there hand & utter "Wrothach"

Upon casting, a large black tentacle reaches out from the casters outstretched hand, lashing at an enemy, dealing 1d8 force damage.

Eldrich Reach allows all spell-casters to tap into Eldritch Power, although not quite as effective as the warlocks that have powers given to them by there Patron directly
(Warlocks can cast Eldritch Reach as a Bonus Action after casting Eldritch Blast)
