Ashara's Temporal Prison

You interrupt the attack or Spell of a target and freeze them and yourself in time briefly. Until this spell ends, neither you or the target may take actions, move or be affected by abilities of other creatures. Any effect that targets either of you during this time takes effect when the spell ends.

Upon the end of this spell you are dealt the damage or suffer the effect of the instigating action without reduction or resistance. Any attacks that were directed at the target while frozen are made at advantage and any saving throws the target must make are made at disadvantage. Following the resolution of all rolls affected by this spell the caster is dealt 4d10 force damage while the target takes half as much.
