Mist-Woven Cloak

Mist-Woven Cloak
Wondrous Item, rare (requires attunement)
This cloak is a masterpiece of Muridae craftsmanship, created by the Mist-Weaver Coven using silk from giant forest spiders and aetheric essence. The fabric is nearly weightless and constantly shifts in color between grey, white, and a faint, glowing blue.
Properties
While wearing this cloak, you gain the following benefits:
1. Mist-Blend: You have advantage on Dexterity (Stealth) checks made while in mist, fog, or heavy rain.
