Time Stop Spell
D&D Description of the Time Stop Spell : This spell seems to make time cease to flow for everyone but you. In fact, you speed up so greatly that all other creatures seem frozen, though they are actually still moving at their normal speeds. You are free to act for 1d4+1 rounds of apparent time. Normal and magical fire, cold, gas, and the like can still harm you. While the time stop is in effect, other creatures are invulnerable to your attacks and spells; you cannot target such creatures with any attack or spell. A spell that affects an area and has a duration longer than the remaining duration of the time stop have their normal effects on other creatures once the time stop ends. Most spellcasters use the additional time to improve their defenses, summon allies, or flee from combat.

I have never used the spell. I have a thought though. If the spell was scribed to scrolls you could cast it in a pinch. Yet not expend a spell slot on it. Perhaps you already spent all your slots.
You could cast teleport and have a cool exit scene. One second the caster is there, then poof, vanished. Maybe drop a eversmoking bottle for effect and confusion.
