If we don't mind deviating from the original version, I wouldn't mind increasing Int and Cha both to 18.
As for wear skeleton, yup, I'm ready. Seems like it should grant a +5 natural armor bonus. Maybe the visceraith should only have a land speed if wearing a skeleton, too. And, finally, some skeletons grant bite or claw attacks. If that sounds right, I'll write it up.
Well, the land speed business was just because they're a mass of dangling organs without appendages. What about a compromise for a 20 ft land speed "naked" and 30 ft with a skeleton? It just makes more sense to me that they could get around better with legs.We also need to add the possibility of a bite attack and increase the claws to 1d6 (per the original). And add a blurb about putting on and taking off the skeleton. Here's a go at it:
Wear Skeleton (Ex): A visceraith can inhabit the skeleton of a humanoid or monstrous humanoid creature of its own size. While wearing a skeleton, a visceraith gains a +5 natural armour, a 10 ft increase in land speed, and two claw attacks (doing 1d6 damage for a Medium-sized visceraith). A skeleton-wearing visceraith can use the skeleton to wield weapons and perform other physical actions. A visceraith requires 1 minute to don a skeleton but only a full round action to remove itself.
Some visceraiths wear alternative skeletons. For example, a visceraith that uses a skull from a creature with a natural bite attack gains a bite attack (1d8 damage?).

Let's also put this in the "spells" entry to prevent confusion:
When wearing a skeleton, a visceraith uses its skeletal limbs to perform somatic components for spells; however, a visceraith without a skeleton can still perform somatic components perfectly by manipulating its internal organs.
I like the jazzing to the spells. You have a gift for description.![]()
I think we're going to need to appeal to Shade on the movement speeds.![]()
I got the impression that they didn't have a land speed in "organs only" form.
Do you think they should be able to fly while wearing a skeleton?
MOVEMENT: 12 or Fly 9 (D)
