Magic Items

Ring, very rare (requires attunement)
While wearing this ring, you regain 1d6 hit points every 10 minutes, provided that you have at least 1 hit point. If you lose a body part, the ring causes the missing part to regrow and return to full functionality after 1d6 + 1 days if you have at least 1 hit point the whole time.
This band of emerald is engraved with the face of a snarling troll. While the ring works to heal its wearer, it radiates a comfortable warmth and the troll head’s expression changes to a wicked grin.
This item can be found in the Dungeon Master’s Guide.

Wondrous item, very rare (requires attunement)
This robe has 3 charges, and it regains 1d3 expended charges daily at dawn. While you wear it, you can use an action and expend 1 charge to cause the garment to display a shifting pattern of dazzling hues until the end of your next turn. During this time, the robe sheds bright light in a 30-foot radius and dim light for an additional 30 feet. Creatures that can see you have disadvantage on attack rolls against you. In addition, any creature in the bright light that can see you when the robe’s power is activated must succeed on a DC 15 Wisdom saving throw or become stunned until the effect ends.
While attuned to this item, the character’s eyes turn a milky white opaqueness, and black ichor collects in the corners of their eyes that can not be wiped away. The wearer has a strong aversion to mirrors and other reflective surfaces, and reacts unfavorably to any criticism due to the unhealthy level of vanity that the robe imparts.
This item can be found in the Dungeon Master's Guide.
