Time stop

Time stop is a transmutation spell that effectively stops time for everyone except the caster.

Effects
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; however, you can create spell effects and leave them to take effect when the time stop spell ends. (The spells' durations do not begin until the time stop is over.)

You cannot move or harm items held, carried, or worn by a creature stuck in normal time, but you can affect any item that is not in another creature's possession.

You are undetectable while time stop lasts. You cannot enter an area protected by an antimagic field, or by protection from chaos/evil/good/law, or by a magic circle spell, while under the effects of time stop.
