Forced Incorporeality?

[snakeman830]

Outside of Epic spells, is there a way to turn another creature incorporeal?  Preferably a method that could feasibly be used in-combat.

This one only affects ghosts or other undead that are usually incorporeal but somehow have become solid.

FORCED INCORPOREALITY
- GHOSTWALK (3.0)
Transmutation [Ectomancy]
Level: Cleric 3, Sorcerer/Wizard 3

The target ghost is enveloped in an orange haze that forces it to be incorporeal for the duration of the spell.

This one only does semi-incorporealness

SHADOW PHASE
- SPELL COMPENDIUM (3.5)
Transmutation
Level: Assassin 4, Sorcerer/Wizard 3
Components: V, S
Casting Time: 1 standard action
Range: Touch
Target: Creature touched
Duration: 1 round/level (D)
Saving Throw: Fortitude negates (harmless)
Spell Resistance: Yes (harmless)
Your hand becomes slightly translucent as you complete the arcane gestures of the spell. As you touch the
intended recipient, your hand appears solid again, while the subject’s flesh takes on a dark, wispy,
insubstantial appearance.
The spell temporarily transposes some of the subject’s tissue with shadow-stuff, making the subject
partially incorporeal. This partially incorporeal state does not allow the subject to pass through walls or
other solid objects. Non-magical physical attacks directed against the spell’s subject suffer a 50% miss
chance. Magical attacks, such as supernatural and spell-like abilities, spells, and magic weapons, suffer a
20% miss chance.

There are several spells that turn the caster incorporeal.  If you have a familiar or animal companion, you can use the share spells power to have the spell affect them instead (or in addition to).

Otherwise, I can't find any way to turn another creature incorporeal.  I guess you could kill them and see if they come back as a ghost ...   

Good luck!

If you find a spell that makes the caster incorporeal but isn't Personal, you could use Ocular Spell.

If the creature you want to force into an incorporeal state is a Cleric or high-level Paladin, you could do the following:

1) Dominate the cleric.
2) Instruct the cleric to pray for the spell redirect spell (Shining South).
3) Instruct the cleric to target a creature* with redirect spell.
4) Have the other creature cast Ghost Form (or any other spell that would make it incorporeal).

The cleric is now incorporeal.

*This creature needs to be able to cast a personal-range spell that makes them incorporeal, such as Ghost Form.  It helps if this creature is an ally of yours; otherwise have it dominated as well.

[Gazzien]

Even if it is personal, you might be able to do something with the Spellguard of Silverymoon's ability to spread "Defensive" personal spells as touch?

Just found another way, but it's not going to help 

Bracelets of Spell Sharing (DMG2, p266) - you can share any personal spell with the wearer of the other bracelet.  The trick is getting the bracelet on your enemy...

Sleight of Hand.

[snakeman830]

Truthfully, what I'm looking at is an inescapable prison involving two spell clocks that cast Antimagic Field in alternating intervals, but their areas overlap.  An incorporeal creature can be imprisoned in that overlapping area until one of the two spell clocks is destroyed/moved.

Hence the necessity of it being combat-viable for turns.

The Sleight of Hand method above would be combat-able

[phaedrusxy]

I know Sleight of Hand is useable in combat, because there were ridiculous flamewars about stripping your opponents naked in combat, and them not being able to do anything about it (the Spot check only lets them notice, not stop you, and you can use it as a free action with a -20 penalty  ). I'm pretty sure there is a rule about using it to plant an object on another person, as well, but I don't see it in the SRD. Maybe it was in Complete Scoundrel or Adventurer, or something like that?

Edit: You do still have to actually make the DC 20 check to steal an object from someone, and with the -20 penalty, that's actually no small feat. So the old threads about being able to put 1 rank in Sleight of Hand, and steal all of someone's gear in combat as free actions are a bit misleading.

[zook1shoe]

One of my defunct game chars has a feat from Dragonlance? that removes the entire -20 penalty

Antimagic field causes incorporeal undead to wink out of existence, but I don't remember anything special happening to incorporeal creatures of other types. 

Also, I'm pretty sure the durations of spells expire even if the creature they're cast on is temporarily nonexistent due to being an incorporeal undead in an antimagic field.

Correct on both counts.

[nijineko]

there are two psionic powers which will accomplish this exact effect, one of which can be offensively used.

my preferred method is the force substantiation power. it transfers a creature to the plane you are on, dimensional anchors them temporarily and strands them on the plane. of course, you'll need a way to get to the plane you're planning on stranding them on (and back). great for ghosts (or against ghosts).
