Weave Anchor

You become chosen by Mystra, the Goddess of Magic, to be a living anchor that stabilizes the Weave where its knots would otherwise cause magic to go awry.

You are immune to the effects of the Dispel Magic and Antimagic Field spells. When you willingly end your Concentration on a spell you cast by expending a spell-slot, its effects continue until the start of your next turn, even if you cast another spell that requires Concentration.
