Entombment

This spell targets one medium or smaller creature in the casters vicinity that the caster can see. The target must succeed a DC 15 charisma save, on a success the target is stunned on a failure the target falls over and is magically put into a casket and the casket that they are in sinks into the ground until the casket is 6 feet under the ground (the sinking takes the length of a players turn). The caster can decide if the casket will suffocate the victim or if it will just keep them in the casket. If the caster decides to slowly suffocate the creature inside the casket then every round the creature will take 6 (2d4 + 2) true damage (unless they don’t need to breathe oxygen in which case they take no damage). If the target dies from suffocating than the caster no longer needs to concentrate on keeping the casket buried. If someone Is inside the casket they can do a DC 21 strength saving throw each turn and if they succeed they will bust out of the casket and be were they where before being magically dumped into a casket.
