Time Trap

Raising your hand and pointing an open palm at a target in range you mutter an incantation tied to the ages themselves as a dome of frozen time forms around your target. The space is a hemispherical dome or a sphere with a radius of up to 20 feet. 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 (the caster’s choice which side).

All creatures within the sphere must make a Wisdom saving throw. On a failure the creature is stunned and incapacitated, suspended in a moment of perfect stillness, even if flying or falling. The creatures may make another save at the end of each of its turns. On a success the creature may simply walk through the wall. The sphere is immune to all damage and can’t be dispelled by Dispel Magic, however a Disintegrate spell destroys the wall instantly. The wall also extends into the ethereal plane, blocking ethereal travel through the wall.
