Aegis of the Watcher Shield

While holding this shield, you are immune to blindness and deafness. The shield has three charges. If you fail a Wisdom (Perception) check, you may instead choose to succeed on it instead by expending one charge. The shield regains 1d2 charges daily at dawn. If you expend the last charge, roll a d20. On a 1, the shield turns to dust and is destroyed.

From Lore of Aetherra: The Lost Druid book.

Shields require the Utilize action to Don or Doff. You gain the Armor Class benefit of a Shield only if you have training with it.

Notes: Immunity: Blinded, Immunity: Deafened
