Eldritch Doom

Prerequisite

eldritch blast cantrip

Description

When you cast eldritch blast, you can cause bolts of mystical power to lash out and savage nearby targets instead of making individual attacks. Any number of targets designated by you within a 5-foot-range must make a Dexterity saving throw. A target takes 1d10 force damage on a failed save, or half as much damage on a successful one. For other eldritch invocations that take effect when eldritch blast hits a target, eldritch blast is considered to hit any target that fails its saving throw.
The range increases when you reach higher levels: 10-foot-range at 5th level, 15-foot-range at 11th level, and 20-foot-range at 17th level.
