Eldritch Invocation: Concentrated Beam

When you cast Eldritch Blast, you may choose to combine all beams into a single overwhelming ray of destructive power targeting one creature you can see within range.

The target must succeed on a Dexterity saving throw against your Warlock spell save DC.

On a failed save, the target takes force damage equal to the combined total of all your Eldritch Blast beams (as if each hit had struck them individually).

On a successful save, the target takes half as much damage.

This singular blast is still considered an Eldritch Blast for the purpose of Eldritch Invocations and other features that modify it (such as Agonizing Blast, Repelling Blast, or Lance of Lethargy). Apply such effects only once, regardless of how many beams are combined.
