Sworn Protector (5e Equipment)
From D&D Wiki
Wondrous item, very rare (requires attunement)
This mechanical insect is made of silver and glass and appears exceptionally fragile. When you take damage, the insect activates and begins buzzing around you. It has 12 hit points, AC 15, and resistance to magical damage. While active, spell attacks that target you have disadvantage, as the insect attempts to intercept them. If this disadvantage causes an attack that otherwise would have hit to miss, the attack hits the insect instead. The insect remains active for 3 minutes, after which you must complete a long rest for it to activate again. During a long rest, the insect magically repairs itself for 3d4 hit points.
