Penance

This is a draft of Penance as a unique "variable half-fiend" outsider, without using class levels. The psionic powers, psi-like abilities and some of the spell-like abilities represent a use of Ki, while others represent actual magic casting ability.  The chaos, entropy and magical writing themed spell-like abilities, as well as the arcane dilettante spell-like abilities, represent the latter.

This is a "very loose and liberal" interpretation of a freeform online RP character that knowingly deviates from normal D&D 3.5 guidelines.

Note: Constant spell-like abilities may only affect the creature possessing them, and remain active indefinitely until dismissed or dispelled. If dismissed or dispelled, each one can be reactivated as a swift action.

SPECIAL ABILITIES
Penance's natural and weapon attacks overcome damage reduction as if chaotic and made of cold iron.
AC Bonus (Ex): Penance may add her Intelligence bonus to Armor Class, so long as she is unencumbered and is wearing light or no armor. This bonus to AC applies even against touch attacks or when she is flat-footed. However, she loses this bonus when she is immobilized or helpless.
Arcane Dilettante (Sp): Penance has a unique understanding of magic, and can mimic spells as a spell-like abilities.
    At the start of each day, she may choose up to 8 spells from the sorcerer/wizard spell list. The maximum level of spell she can use is 7. She can select any sorcerer/wizard spell up to that level, but can prepare only one spell of that maximum level. Her caster level equals her Hit Dice. The DC for a saving throw against these spells are intelligence based.
    Once she has cast a particular spell, she cannot use it again until she has have rested for 8 hours. After resting for this time, she can choose new spells and lose any unused spells from the previous day, though she can select the same spell on consecutive days. She cannot prepare the same spell multiple times to use it more than once during the same day. She cannot use spells that require an XP cost.
    If she wishes to enhance a spell with a metamagic feat, she must apply the feat when she prepares the spell. In addition, she must be capable of using a spell of the modified spell’s level.
Brains over Brawn (Ex): Penance gains her Intelligence bonus as a modifier on Strength checks, Dexterity checks, and checks involving skills based on Strength or Dexterity, such as Hide, Climb, and Jump.
Human Form (Su): Penance may assume a single specific human form as a full-round action. She can dismiss this form as a free or immediate action. She retains her physical ability scores while in this form, but loses all extraordinary attack forms, natural armor, movement speeds and racial bonuses that rely on her normal fiendish anatomy. She retains her 80 ft. land speed in this form.
Insightful Strike (Ex): Penance is able to place her finesse attacks where they deal greater damage. She applies her Intelligence bonus (if any) as a bonus on damage rolls (in addition to any Strength bonus she may have) with any light weapon, as well as any other weapon that can be used with Weapon Finesse, such as a rapier, whip, or spiked chain. Targets immune to sneak attacks or critical hits are immune to her insightful strike. She cannot use this ability when wearing medium or heavy armor or when carrying a medium or heavy load.
Ki Power (Su): Penance can channel her ki to manifest special powers. She can use her ki powers a number of times per day equal to one-half her HD (minimum 1) plus her Wisdom bonus (if any). These Ki powers can be used only if Penance is wearing light or no armor and is unencumbered.
As long as a her ki pool isn’t empty (that is, as long as it has at least one daily use remaining), Penance gains a +2 bonus on its Will saves. (not figured in stats above)
    Martial Renewal: Once per round as a standard action, Penance may expend one daily use of her Ki power to recover any single expended martial maneuver she knows.
Maneuvers and Stances Known (Ex): Penance starts each encounter with all the maneuvers she knows readied. For maneuvers that feature a saving throw based on strength, she may use her intelligence instead.  She may recover the use of all expended maneuvers by resting for 2 minutes.
Regeneration (Ex): Penance takes lethal damage from lawful weapons and spells and effects with the lawful descriptor. She can otherwise regrow a lost limb in 6d4 hours, or reattach a severed limb by holding it to the stump for 1 round. If her head is separated from her torso, she dies normally.
