Ring of Magical Girl Transformation

A white-coloured ring, engraved with an adorable cat face.

When the user is attuned to this ring, they can spend 10 minutes concentrating to store the armour they are wearing. 

When the user does this, they are left in whatever simple clothing they wear under their armour, and the armour is safely transported inside a pocket dimension inside of the ring. If weapons are stored in parts of their armour, those weapons appear in an orderly pile in front of the user. 

The user can equip the stored armour by holding out their ring hand, then making a fist and focusing on the ring. This costs the user one action and one bonus action if used in combat.

When a charge is expended, a "magical girl" transformation takes place, wherein the user is encircled in a colourful aura, with the stored armour parts appearing consecutively as outlines over the users body, which glow brightly before being becoming corporal. The transformation is accompanied by a compelling musical sting and cannot be interrupted. Armour can be dismissed to the ring as a bonus action.

For the next hour, the user can add 1d4 to the next persuasion check they make.

Notes: Bonus: Persuasion, Jewelry, Outerwear, Handwear, Bard, enchantment
