Capture Creature

This spell allows its caster to seal any creature or object of size small or smaller in a container. The container must have a lid or seal. The lid or seal must be placed on the container within one turn after capturing the target, or the creature will escape. The container does not have to be a container that could regularly fit the creature. For example, a human could be sealed within a jar. After casting, the user takes a whole turn to force the creature into the container of choice. The user and the target cannot move or take any action while the spell is in progress. The creature must make a wisdom save or it will be held in place. If the creature cannot be freed after one turn, it must make a successful constitution saving throw or it will be captured inside the container. The creature is in a constant state of stasis while captured, meaning it is constantly incapacitated. However, the create cannot be targeted by any outside spells that are not currently affecting it, and it is considered to be on a separate plane. Should a creature be successfully captured, it can then be released by opening or destroying the container. The creature will appear in the place of the destroyed container.
