Anneau de l’Oeil Scrutateur

This obsidian circle engraved with a black eye seems to pulsate under the wearer's skin.

Effect:

Once per turn, when you fail a spell attack roll, you can choose to re-roll the die.

You must keep the second result.

Each time you use this effect, you suffer 1 point of necrotic damage.

This ring is imbued with a force that seeks to push you beyond your limits... at a price.

Notes: requires attunement by a spellcaster
