Found in the Temple of the Three - Torm, Tyr, and Ilmater - that was buried under Elturel and came to be partially exposed on a cliff side when Elturel fell down into Avernus.
The bracelet was a gift from Ilmater to her High Priest in Elturel.
When The Companion's crusaders tried to destroy the temple, the angel VeDa'la burrowed the entire temple underground, laid protective spells to keep unwanted trespassers out and have been guarding it and the relics in it ever since.

While wearing the Bracelet of Ilmater you gain the following features:

• You have advantage on Initiative rolls.
• You have advantage on Wisdom (Insight) checks.
• You are compelled to spare enemies that ask for mercy.

This bracelet has 10 charges. While wearing it, you can use an action to expend 1 or more of its charges to cast one of the following spells from it, using your spell save DC and spellcasting ability modifier: Cure Wounds (1 charge per spell level, up to the highest spell level available to you), Lesser Restoration (2 charges), or Revivify (3 charges).

The casting of Cure Wounds using this bracelet is an act of mercy and self sacrifice. You suffer damage equal to half the amount healed, rounded down.

The staff regains 1d6 + 1 expended charges when you act in a manner that pleases Ilmater: when you do something to advance Ilmater’s interests or behave in accordance with Ilmater’s ideals.

Notes: Advantage: Insight, Advantage: Initiative, Healing
