Sunken Souls Template
Sunken Souls are those who have had their souls removed from their body from binding magic and now remain as husks. They do nothing but stay alive; breathing, eating, and sleeping.

Creating a Sunken Soul
Sunken Soul is an "acquired" template that can be added to any non-elemental or outsider creature (refered to hereafter as the base creature).

A Sunken Soul uses all the base creature's statistics and special abilities, except as noted here.

Size and Type
Type and Size are unchanged.

Hit Dice
A Sunken Soul loses all class levels, adjust; Hit Dice, Skills, Feats, and Proficiencies accordingly.

Speed
All forms of movement the base creature has drop to 5ft (1 square).

Special Qualities
The base creature keeps its Special Qualities in addition to gaining the following:

• Mindless: No Intelligence score, and immunity to all mind-affecting effects (charms, compulsions, phantasms, patterns, and morale effects).
• Soul Drained: Immune to all Death Effects, Imprisonment, Trap the Soul, and all binder class features except for Sunder Apparatus.

Abilities
All ability score remain normal, except for intelligence which is lost as a Sunken Soul is mindless.

Feats
A Sunken Soul loses all Feats it would have obtained by obtaining class levels.

Challenge Rating
As base creature -2.

Treasure
None.

Alignment
The Base creatures alignment changes to Neutral.

Level Adjustment
N/A.

Note
If the soul is returned to the base creature by use sunder apparatus ability then this Template is lost and the base creature regains everything that was lost in gaining this template.

"Archaic" means old. It doesn't mean related to law.

"Archaic" means old. It doesn't mean related to law.

Confused it with Axiomatic. I've now fixed it.

[Milo v3]

Any info on whether or not these seem balanced or any ideas for new ones?

[radmelon]

There is quite a bit of overlap among the feats, and "Angels", "Celestial", "Demon", "Devil", and "Fiendish", aren't subtypes. Might wanna fix that.

Angel Subtype does exist actually. Demon and Devil are the SRD name for Baatezu and Tanari subtypes.

You are right about the Celestial and Fiendish though. I'll fix it.

While the "angel" subtype does exist, the feat repeatedly states "Angels" subtype. Just a bit of nitpicking going on.

Fixed. Also nitpicking is appreciated. I want my work to be as good as possible.
