Eldritch invocation: Nearfield Nexus

Prerequisite: 7th level, eldritch blast cantrip

Being within 5 feet of a hostile creature does not impose disadvantage on your eldritch blast attack rolls. Additionally, when a hostile creature enters your melee weapon reach, on your next turn you may cast eldritch blast as a bonus action, or instead of one of your attacks made as part of the Attack action, against any hostile creatures within your melee weapon reach.
