Ring of Mystic Protection
wondrous item (ring), rare (requires attunement)
This white gold ring bears a square-cut ruby. Arcane runes are inscribed around its band.
A Ring of Mystic Protection protects you from damaging magical effects. When you use a reaction to expend a change from the ring, you ignore 3d6 damage dealt by a spell or spell-like ability. You can activate the ring after you learn the damage a spell or spell-like ability will deal to you, but before the damage is actually dealt. This ring has 4 charges and regains 1d4 expended charges each day at dawn. If all charges are expended, roll a d20 and on a roll of 1, the ring loses its magical powers.
