Vitriolic Blast

Prerequisite

eldritch blast cantrip

Description

As a bonus action, you conjure volatile acid that drips from your fingertips. The next time you cast eldritch blast, each of its attacks deal acid damage instead of force damage. Each target hit by these attacks takes an additional 1d6 acid damage at the start of your next turn. These attacks are formed from conjured acid, making them different from other eldritch invocations in that all acid damage dealt by these attacks ignores magic resistance.
You lose the benefits of this eldritch invocation if you use a different eldritch invocation that changes the damage type of your eldritch blast before you cast the cantrip.
