Eldritch Glaive

Least Invocation
Blast Shape
2nd Level Spell

Your eldritch blast takes on the physical form of a glaive. If you hit, your target is affected as if struck by your eldritch blast (including any eldritch essence applied to the blast). If your base attack bonus is +6 or higher, you make as many attacks with your eldritch glaive as your base attack bonus allows. For example, a 12th-level warlock could attack twice, once with a base attack bonus of +6, and again with a base attack bonus of +1.
