Boon of Antimagic

Epic Boon Feat (Prerequisite: Level 19+)

You gain the following benefits.

Ability Score Increase. Increase one ability score of your choice by 1, to a maximum of 30.

Antimagic Aura. An aura of antimagic surrounds you in a 10-foot radius. No one can cast spells, take Magic actions, or create other magical effects inside the aura, and those things can’t target or otherwise affect anything inside it. Magical properties of magic items don’t work inside the aura or on anything inside it.

Areas of effect created by spells or other magic can’t extend into the aura, and no one can teleport into or out of it or use planar travel there. Portals close temporarily while in the aura.

Ongoing spells, except those cast by an Artifact or a deity, are suppressed in the area. While an effect is suppressed, it doesn’t function, but the time it spends suppressed counts against its duration.

Dispel Magic has no effect on the aura. The auras created by Antimagic Field spells don’t nullify the aura and aren't nullified by the aura. You can suppress or activate this aura as a bonus action.
