Classes
• (Ability Name) at-will = Spell-Like Ability, at-will unless specified otherwise
• (Ability Name) X/day = Number of times a Spell-Like Ability may be used in a day

Transcend (Ex): The character may assume the form and appearance of a specific monster race for each one named. Only one specific type of Transcend form may be assumed each day.
After a full sleep period (one night) the character may switch to or from a previously known Transcend form, readying it for use throughout the day and until switched again.
Activating form abilities and appearance takes 1 round of concentration. Switching back is 1 standard action.
While a form is active add all specified traits to the character. Everything else stays the same.
Spell-like and supernatural abilities of the monster are available while the form is active, but class-based spells from the monster are not. For instance a Solar form does not grant Cleric spellcasting. A monster form's spell-like abilities with limited uses remain expended until after a full sleep period even if forms are changed.
Spell-like and Supernatural abilities use the character's total levels as caster level for effects.

Fiendish Adaptation (Ex):
Add each class level to Natural Armor bonus.
Add every even class level as a racial bonus to each ability score.
Ability score bonuses granted by this ability do not stack with racial or enhancement bonuses.

Wings (Ex): The character has wings that vary in ability from decorative to fully functional.
Level Flight
1 as Feather Fall
3 Glide speed 30 (Average, fall 5 feet every round, no upward motion)
5 Fly speed 60 (Good)
9 Take no nonlethal damage from Hustle action while flying

Change Shape (Su): As Disguise Self but the character's body is physically altered as a Transmutation effect. Only humanoid forms of the same size or one smaller may be taken. Natural attacks are changed to that of the assumed species.

Fear Aura (Su): Devil, Level 10+. 5 foot aura created as a free action. All affected must pass a Will save DC 10 + 1/2 level + CHA or become Panicked for 1 round per level, success means the being is Shaken for 1 round per level. If the save was passed, a being can not be affected for 24 hours.

[JonSetanta]

Perhaps I should remove the "Fiend" part of these classes.

The next step is to provide some fiendish base races with scaling defensive abilities, maybe some increasing stat boosts (racial, inherent bonuses, etc)

They won't be as powerful as the monsters they were derived from, but hopefully close.

[JonSetanta]

Updated, made some minor changes to names, SLA placements, etc.

Hope the Cenobyte and Ravager goes over well.

[JonSetanta]

Added Yugoloth Mercenary class, some changes to SLAs and other things.

Fixed Transcend wording.

[JonSetanta]

Moved Animate Undead for Dark Lawyer from level 1 to 5.

[CatharzGodfoot]

So what's the point of giving out both highly limited sorcerer casting and a bunch of spell-like abilities (which are often drawn from the same pool of spells)?

Also: the Dark Lawyer should probably get spells from the Pact domain, and adding the Evil domain to the Tanar'ri Ravager and the Yugoloth Mercenary only adds one possible spell known (unholy blight).

[JonSetanta]

The sorcerer casting is optional, and player-controlled. The SLAs are core to the class function and the same between each member of the same class.

Is Pact domain core?

Also, I provided Darkness for devils early on because it needs to be done.
Otherwise their sight ability goes to waste. Why the fuck do demons get darkness? Pointless.

[JonSetanta]

Did an overhaul with Transcend (it works like a Polymorph fix now) and changed the later 4 classes to PrCs.
Removed a lot of SLAs.
