Time Trap (5e Spell)
From D&D Wiki
|Casting time:||1 action|
|Duration:||Concentration, up to 10 minute|
Raising your hand and pointing an open palm at a target in range you mutter the Astral words for Time, Stop, and Trap as a dome of Astral Energy forms around your target, time within the dome has stopped flowing. The hemispherical dome or a sphere with a radius of up to 10 feet, or you can shape a flat surface made up of ten 10-foot-by-10-foot panels. In any form, the wall is 1/4 inch thick. It lasts for the duration. If the sphere cuts through a creature’s space when it appears, the creature is pushed to one side of the sphere (your choice which side).
All enemy creatures within the sphere must make a Wisdom saving throw, on a failure the creature is stunned. The creatures may make another save at the start of each turn it is trapped in the sphere. The sphere is immune to all damage and can’t be dispelled by dispel magic. A disintegrate spell destroys the wall instantly, however. The wall also extends into the Ethereal Plane, blocking ethereal travel through the wall. On success they may just walk through the wall.
