Death strike

It puts your enemy into a torture like state for 72 hours in that world but in reality is only an instant. With every day your target is trapped in the world of torture it takes 2 d12 damage by each time it takes damage it can make a intelligence saving throw if the target succeeds it take half the damage. When the caster casts this spell it is put in the same state but doing the torturing if either of these targets gets hit by the spell they are both released from the spell but take  1 d20 damage
