Wondrous Item

Very Rare Requires Attunement

You have advantage on Saving Throws against Spells while you wear this cloak.

This item has been enhanced by intricate embroidery of quicksilver thread on the inside of the cloak, reminiscent to the branching neurons within a brain. While you wear this cloak, you may use a reaction to negate a counterspell directed against a spell you cast from the school of enchantment.  Once it is used in this way, you cannot do so again until you finish a long rest.
