Otiluke's Resilient Sphere

When a wizard casts Otiluke's Resilient Sphere, he encloses a creature in a globe of shimmering force.
==Description==
==Gameplay==
The caster directs this spell at a single creature in range, including self.
When the casting is finished, the spell attempts to apply the sphere upon the creature - if the target is under the control of the party, or a party member, or cast on self, then the sphere is applied. 
If the target is unwilling, or isn't a party member, then the creature is allowed a Saving throw versus Spells to negate the sphere.
This spell is flagged as "Hostile" if cast on non-party targets- it will "agro" neutral creatures in the vicinity of the spell cast, even if the target makes their saving throw.
Unwilling targets can block this spell with Magic resistance, or Spell Immunity: Alteration, and any spell protection with the capacity to withstand a 4 spell Power level effect, such as Minor Spell Deflection, Minor Spell Turning, or Globe of Invulnerability.
When this sphere is applied to a creature the following will occur:
* A shimmering globe graphic is rendered over the creature.
* Hold creature 2 effect applied (not to be confused with the much more common Held effect)
* Protection from 27 specific spells (such as Incendiary Cloud and including some effects from Wish),
* Improved Invisibility
* Set attacks per round to 0
* Set movement rate to 0
* Immunity to damage
* Immunity to magical weapons
* Immunity to normal weapons
* Immunity to all spell schools
* Immunity to spells and effects from levels 1 through 9
* Immunity to several secondary spell types (e.g. "offensive damage", "disabling")
* Immunity to poison
* Set poison, (magical) fire, (magical) cold, electricity, acid, magic, slashing, crushing and piercing damage resistance to 100
* Set magic resistance to 100
So, in summary the sphere will make a creature invisible, un-targetable, immobile, and unable to act in any way for the duration of the spell, and all the while the sphere prevents harm to the creature inside it.
Despite all of this, you can still be "hit" by a few abilities that can have certain side-effects. For example, a dragon's Wing Buffet is a nonmagical effect that can still "hit" (for no damage) the protected character through the sphere and can even inflict its short duration nonmagical "unconsciousness" effect on the character. 
A few noteworthy consequences of this are the fact that such abilities that "hit" you through the sphere: 
a) Will trigger contingencies with the condition "hit". 
b) Will cause a Project Image clone to disappear, if the "hit" character is the one who originally cast the spell. 
As of version 2.6 of the Enhanced Editions, this spell has been changed so that there's no save against the effect when cast on an ally or yourself. This includes so-called "GoodButRed" (as they're referred to behind-the-scenes) creatures who are technically allied to the party, but have red circles, such as the Demons gated in by the spells Cacofiend, Summon Fiend and Gate. That means you can easily (i.e. without a save and ignoring magic resistance) stop them after they've served their purpose by casting Otiluke's Resilient Sphere on them.
This spell can be removed with any Dispel Magic effect.

==Mod content==
Spell Revisions mod has changed this arcane spell, revising its saving throw and description. See below for description:
Otiluke’s Resilient Sphere
Level: 4
School: Alteration
Range: Long
Duration: 1 turn
Casting Time: 4
Area of Effect: 1 creature
Saving Throw: Spell negates
When this spell is cast, the result is a globe of shimmering force that encloses the subject creature if it fails to successfully save vs. breath at a -4 penalty. The resilient sphere will contain its subject for the duration of the spell. The sphere is completely immune to all damage. Actually, the only method of removing the sphere is a successful dispel magic. Hence, the creature caught inside the globe is completely safe from all attacks, but at the same time is completely unable to affect the outside world.
The caster has the option of using the spell to protect her allies. Resistances and saving throws are bypassed when the target is willing.
