Soulbind Wild Spirit (3.5e Invocation)

When you use this invocation you summon a phantasmal humanoid fey spirit who may be haunting beautiful or twistedly hideous. It floats just behind you in your square. The creature is technically a projection, though it can be dismissed or banished as if it were a separate outsider creature. However you can just re-summon them next round. Unlike most invocations, you can only have one soulbind invocation active at one time. Using another one causes the first to vanish.

While soulbound to the wild spirit you count as a fey for the purposes of interacting with spells and effects such as a ranger's favored enemy, and count as chaotic alignment (as well as a member of your original alignment), both for good and ill. While soulbound to this invocation you gain access to the following abilities.

Ally of Nature : You are not affected by any natural terrain or hazards, such as slowing down in a bog, entanglement in plants, or burning in lava. You are not immune to the effects of gravity, so falls can still kill you. Magical effects and magically altered terrain still effects you, but you get a +4 bonus on any saves against it.

Damage Reduction : You gain damage reduction/cold iron equal to 1/3rd your caster level. This stacks with pre-existing DR/cold iron you may possess.

Dance of Madness : As a full attack action you may prance wildly, causing a confusion effect centered on you (you are excluded, but your allies are not). The DC is 15 + Cha modifier.

Illusive Painting : You can duplicate the effects of major image at will.

Favored Enemy : You gain the favored enemy ability of a 5th level ranger against aberrations and constructs. You decide which has a +4 bonus and which has a +2 bonus when first casting soulbind wild spirit.
