Snatch Spell vs Planar Ally

[Tindragon]

Can an Incantatrix use Snatch spell to take a PLANAR ALLY away? RAW?

Snatch Spell (Su): At 8th level, an incantatrix can attempt to seize control over a persistent effect created by another spellcaster. The effect must be one that does not depend on concentration but still relies on or responds to the caster's control (such as a summon monster spell or spiritual weapon, but not a wall of fire or acid fog). Furthermore, the effect (but not necessarily the spellcaster) must be within 30 feet of the incantatrix. The target spellcaster and the incantatrix make an opposed caster level check. A divine spellcaster receives a +2 bonus on this check. If the incantatrix wins, she gains control of the spell until its original duration expires. The spell functions as though the incantatrix had cast it, except that any variables determined when the spell was cast (including its caster level) remain as determined by the caster. The original caster can be affected by his own spell, though he receives a +2 circumstance bonus on any saving throw allowed against it. If the spell is dismissible and the incantatrix wishes to dismiss it, she must make a second successful opposed caster level check to do so. If she fails, the spell remains in effect and control reverts to the original caster.

Hard to say. Planar Ally is Instantaneous, so it doesn't really have a duration.

I'm leaning toward "no".

Nope.

Bolded everything that makes it not work. Planar Ally doesn't have a persistent effect. All it does is bring the outsider to you. Past that, there's no magic. just like how you can't dispel a Wall of Stone, you can't Snatch a Planar Ally.

Planar Ally also doesn't respond/rely on caster control. Once you Call the outsider, it acts entirely of its own initiative, regardless of what the caster does. Second off, the incantatrix only gains control of the spell for the rest of its duration. Since Planar Ally is instantaneous, that duration was long over by the time you could Snatch it.

tldr: Nothing Instantaneous can be snatched, because whatever resulted isn't a spell effect anymore.

Awesome, thanks.
