Shawl of the Snowbird

Wondrous item, very rare (requires attunement)

This crocheted wrap of white woolen yarn is decorated with a fringe of woven tassels and decorated with embroidered feathers. While you wear it, you gain the following benefits:

• You are unaffected by cold temperatures up to -50 degrees Fahrenheit, or -100 degrees Fahrenheit if you are also wearing heavy clothing.
• You have advantage on Dexterity (Stealth) checks made in arctic terrain or in snowy or icy areas, and you may make Dexterity (Stealth) checks to hide in such terrain even when you are being directly observed.
• If you have the ability to polymorph or change shape into a bird or feathered creature native to arctic or cold environments, the duration of the effect is doubled, and other creatures have disadvantage to sense the form is false.
• You can perform a hypnotic feather dance with the shawl, causing creatures within 20 feet who can see the dance to become charmed unless they succeed a DC 17 Wisdom save. You can’t affect more than 24 Hit Dice worth of creatures with this effect. You can maintain the dance each round instead of moving, or you can use your action to release feathers from the shawl that flit and float in a dancing silhouette resembling you, flying away 20 feet per round in a direction you choose. Creatures affected by the dance follow the dancing feathers, perceiving them to be you enticing them on a wondrous adventure. Once used, this property of the shawl can’t be used again until the next dawn.
• When you would be struck by an attack, you can use your reaction to discorporate into a swirling mass of white feathers and maintain this form for up to 1 minute. You are treated as though in gaseous form. If you can assume the form of a bird native to arctic or cold terrain, including having beast shape prepared, you may use that ability or cast that spell at any time while in this feather form as a bonus action that does not provoke attacks of opportunity. If you do, your new bird form is surrounded by a cloud of feathers until the end of your next turn, granting you partial concealment without hampering your own vision.

Skeleton Cage

Wondrous item, very rare

This tiny framework of bones can be activated once per day with a command word (spoken within 30 feet), causing it to expand into a Gargantuan skeletal ribcage firmly fixed to the ground and studded with jagged bony shards (AC 20, 80 hit points, condition immunities blinded, charmed, deafened, exhaustion, frightened, paralyzed, petrified, poisoned). Creatures in the area as it expands must succeed on a DC 17 Dexterity saving throw to move to the nearest open space adjacent to the skeleton cage (this does not provoke opportunity attacks).

Failure means the target is grappled (Escape DC 20) and takes 7d8 piercing damage.

The skeleton cage possesses a pair of 20-foot-long skeletal arms that allow the options allowed when grappling a creature. You may direct the arms as an action; otherwise, they attack the nearest creature(s) other than you. Creatures attempting to escape the cage’s grapple take 7d8 piercing damage on a failed save or half as much on a successful one (DC 17). A skeleton cage can hold up to 1 Gargantuan, 3 Huge, 8 Large, or 64 Medium or smaller creatures.

If the skeleton cage is filled to capacity, creatures dragged to it by the hands are crushed against it, suffering damage as above, but are then dropped in an adjacent square. A skeleton cage lasts for 1 hour or until destroyed or commanded to shrink.

Destroying an arm does not harm the skeleton cage, but destroying the skeleton cage destroys the arms. Creatures within a skeleton cage when it is destroyed or commanded to shrink are freed automatically but suffer damage as if attempting to escape it as above. If destroyed in its miniature form (AC 6, 13 hit points, condition immunities blinded, charmed, deafened, exhaustion, frightened, paralyzed, petrified, poisoned), a skeleton cage is permanently destroyed; otherwise, any damage it suffers is repaired the next time it is activated.
