Lissok’s Snow Globe

7-level Enchantment (ritual)

You create a magical restraint to hold a creature that you can see within range. The target must succeed on a Wisdom saving throw or be bound by the spell; if it succeeds, it is immune to this spell for 24 hours. While affected by this spell, the creature doesn’t need to breathe, eat, or drink, and it doesn’t age.
The target shrinks to a height of 1 inch and is imprisoned inside a glass sphere. Light can pass through the sphere normally (allowing the target to see out and other creatures to see in), and sound can travel from outside into the sphere but it cannot travel out.
The creature contained within the globe takes 10 (3d6) cold damage at the start of each of the caster's turns. A creature reduced to 1 hit point in this way stops taking cold damage. A creature within this sphere cannot regain hit points while within the sphere by any means.
The sphere has an AC equal to the caster’s Spell save DC and HP equal to the caster’s spell attack modifier. The magic is dispelled if the globe’s hit points are reduced to 0.
