Changes

This eldritch essence invocation allows you to change your eldritch blast into a beshadowed blast. Any living creature struck by a beshadowed blast must succeed on a Fortitude save or be blinded for 1 round + an extra round per 3 4 warlock levels. When greater invocations are known, the blast can now affect blindsense and blind sight. When dark invocations are known tremorsense is affected.
