House-ruled Time Stop

[Kraedin]

This is the version of time stop I am planning on using in my next campaign. What to people think? Too strong? Too weak? Just right?

Time Stop
Transmutation
Level: Sor/Wiz 9, Trickery 9
Components: V
Casting Time: 1 full round
Range: Personal
Target: You
Duration: 1 round (see text)

This spell seems to make time stop for everyone but you. In fact, you speed up so greatly that all other creatures seem frozen, though they are actually moving at their normal speed. On the round after this spell is cast, you may take 1d4+1 additional partial actions. Time stop stacks with haste. While time stop is in effect, you cannot enter dead magic zones or antimagic fields. Time stop dispels slow, and slow dispels time stop.

A slowed person can interact with a hasted person, albeit at a great disadvantage. Can people moving at normal speed interact with someone in a time stop, or vice versa? Or are they frozen in place and protected by a "force-field" as with the standard Time Stop?

You can attack people, damage people, ect. in my version of time stop. It basically works like a 1 round haste that gives more partial actions.

Ok- so what bonuses will the caster enjoy? To AC, attack rolls and so on. The caster will still draw attacks of opportunity if he moves through threatened areas, right?
