Bracers of Spell Reflection (Patreon)

Wondrous item, very rare (requires attunement by a monk)

While wearing these mirrored bracers, you gain a +2 bonus to AC if you are wearing no armor and using no shield. In addition, you have advantage on saving throws against spells.

While wearing the bracers, you can use your Deflect Missiles feature when you're hit by a ranged spell attack, reducing its damage as if it were from a ranged weapon. If you reduce the damage to 0, you don't suffer any of the spell's effects and can immediately reflect the spell back at the attacker. The reflected spell uses the same spell attack bonus and spell save DC as when it was originally cast.

"Haha! I am rubber, you are glue! Spells you cast bounce back at you!"

"...I feel like slinging childhood rhymes around mid-fight isn't as intimidating as you think."

"Psh! Sticks and stones may break my bones, but words can never hurt me!"

"...I literally know a magic word that can kill. Try to bounce that one back."
