Magic Missile, Shield, & Spell Turning

[The Elusive Jackalope]

If a character is under the effects of both shield and spell turning and gets targeted with magic missile, what occurs?

Is the magic missile turned or negated?

Shield:

Shield creates an invisible shield of force that hovers in front of you. It negates magic missile attacks directed at you. The disk also provides a +4 shield bonus to AC. This bonus applies against incorporeal touch attacks, since it is a force effect. The shield has no armor check penalty or arcane spell failure chance.

Spell Turning:

Spells and spell-like effects targeted on you are turned back upon the original caster. The abjuration turns only spells that have you as a target. Effect and area spells are not affected. Spell turning also fails to stop touch range spells. From seven to ten (1d4+6) spell levels are affected by the turning. The exact number is rolled secretly.

When you are targeted by a spell of higher level than the amount of spell turning you have left, that spell is partially turned. Subtract the amount of spell turning left from the spell level of the incoming spell, then divide the result by the spell level of the incoming spell to see what fraction of the effect gets through. For damaging spells, you and the caster each take a fraction of the damage. For nondamaging spells, each of you has a proportional chance to be the one who is affected. If you and a spellcasting attacker are both warded by spell turning effects in operation, a resonating field is created. Roll randomly to determine the result.

RAW, not certain, but I suspect it gets negated. When unsure of the stacking of certain magical abilities, choose the one that benefits the creature the most. I would say not using up spell turning is the most beneficial, so that's why I would go with that.

I go by what spell effect the missile would hit first.

Spell Turning is on the body of the caster, the Shield spell floats outside of it.

The magic missile is negated, and spell turning never comes into play.

[Obirandiath]

Agreed. The missile should be negated by the shield before it gets to the turning.

I agree with Lazar. Spell turning is not activated until the caster is potentially affected.

That was the call I made last night when it came up; I was hoping to confirm it. Thank you.

[The Bald Man]

I agree. I would call for a Spellcraft check from the character under the effects of both. If they successfully make the check to ID the incoming spell then they get their choice.
