Hat of the Hermit Hag

Wondrous item, uncommon (requires attunement)
  Though this headpiece may easily be mistaken for an average conch, its external dimensions bely its roomy interior. It is much bigger on the inside. Hermit hags love to decorate it with trophies and trinkets traded, tricked, or otherwise taken from unfortunate adventurers.
  While wearing this hat you can invoke it to cast the following spells (save DC 13):
  • disguise self (1st-level)
  • suggestion (2nd-level)
  When you use the hat to cast a spell, roll a d3. If the result is equal to or lower than the spell’s level, the hat can’t be used to cast any spell again until the following dawn.
  Hermit. As a bonus action or reaction to being targeted by an attack, a Small or smaller creature can hide in the hat. Until it emerges, it gains total cover from all directions, has its speed reduced to 5 feet, is blinded, has disadvantage on all Wisdom (Perception) checks, and automatically fails Dexterity saving throws. To emerge from the hat, the creature within must use its action. Knocking the creature prone whilst it’s in the hat exposes its vulnerable underbelly, removing the total cover.
  Rare variant: Increase the DC to 15 and the d3 to a d4. Add the bends (3rd-level) to the spell list.
  Very rare variant: Increase the DC to 16 and the d3 to a d6. Add the bends (3rd-level) and lungburst (6th-level) to the spell list.
