While you are attuned to this item, if you are hit by a spell attack you can use your reaction to absorb the spell into the amulet. When you do so, you must make a Wisdom save against the spell. The DC of this save is 12 + the level of the spell.

If you succeed on the saving throw, you may store the spell in the necklace and make a spell attack (range of the spell) with the absorbed spell. You make this attack with proficiency, and use your Wisdom modifier with proficiency for the Spell Attack. The DC save for the spell is equal to 8 + your Wisdom Modifier. You may store up to two spells in this necklace. You cannot absorb a third spell until you spend one of the stored spells.
