Amulet of the Sea

The amulet has 10 charges. While holding 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:  Wall of Water (3 charges),  Ice Knife (1 charge), Water Breathing (3 charges), Create or Destroy Water (2 charges), or Shape Water (1 charges).

The staff regains 1d6 + 4 expended charges daily at dawn. If you expend the last charge, roll a d20. On a 1, the staff turns to water and is destroyed.

Notes: While attuned to this item, the creature can do this.
