Tattoo of Spell Turning

Wondrous item (tattoo), rare (requires attunement)

When you are the target of a spell or spell attack that targets only you, you can choose either to make your saving throw against that spell with advantage, or that the spell attack has disadvantage against you, and the tattoo disappears. If you successfully save against the spell or the spell attack misses you, the spell has no effect on you and instead targets the caster, using the slot level, spell save DC, attack bonus, and spellcasting ability of the caster. If the spell requires concentration, it lasts until the end of the caster’s next turn, even if they choose not to maintain their concentration on it.
