Armor (shield), rare (requires attunement)

A flat black shield that feels cool to the touch. It seems to absorb the light around it.

This shield has 4 charges.

You can expend 1 charge to cast the darkness spell without needing material components centered on the shield.
You can expend 2 charges to cast the disintegrate spell without needing material components. When you make the spell's attack, you do so with a bonus of +7.

Whenever you expend the shield's last charge, roll a d20. On a 1, the shield shatters, casting the darkness spell centered on you, which lasts for 2d6 hours.

The shield regains 1d4 expended charges daily at dusk.
