Orb of Containment

4th-level evocation

Casting Time:1 action
Range:30 feet
Components:V, S, M (1,000-gp diamond and a shard of glass)
Duration:24 hours

When cast, choose a point within range. You create a crystal sphere up to 12 inches in diameter that surrounds and secures anything within it. The spell fails if you attempt to secure a portion of a larger solid object, but can entrap part of a liquid or gas. The sphere is unbreakable, able to contain any substance no matter how volatile or inimical to life. Time is suspended within the sphere.

The sphere is immune to all physical attacks, though dispel magic can destroy the orb. The material components for this spell are a 1,000-gp diamond and a shard of glass. The diamond shatters when the sphere is created. You can recast the spell before it ends to renew the sphere using only a shard of glass.
