Amulet of Shielding

A golden necklace with a small enchanted blue opal. You can use this magical amulet twice per long rest to trigger its effect: Shield spell.

When an attack hits you, an invisible barrier of magical force appears and protects you. Until the start of your next turn, you have a +5 bonus to AC, including against the triggering attack, and you take no damage from magic missile.
