Time Snare

Upon casting this spell, the caster creates a time loop in the creature's mind that causes it to repeat this round's action indefinitely. 

If the creature attacked, it attacks the same person again. If it drank a potion, it drinks from the same bottle again. Even if something happens to prevent this attempt (the opponent is dead, or someone takes the bottle away), the subject still strives to repeat its last action. The victim makes an intelligent save vs your spell DC at the end of every round; it is affected by the spell until the loop is broken.
