Making Ponyfinder a Reality

[aylatrigger]

So with the coming of Season 2 of My Little Pony: Friendship is Magic, my friends and I are going to do a Ponyfinder campaign based off the joke races found here: http://forum.rpg.net/showthread.php?569049-What-the-hell-Paizo
My brother, who is a Munchkin, and I looked at this and thought: Well what are these Cutie Mark rules found on 'page 35'? We were disappointed when we found out it was just a joke. So we decided to make our own rules.
So far, we figured based on the show a cutie mark has three main points: it can give you a couple traits, be it magical (Twilight Sparkle when she got her Cutie Mark was given some spells) or mundane; you must follow some type of rule, much like the Wu Jen's rules from Oriental Adventures 3.5; and if you break this rule you suffer 'Cutie Mark Insanity Syndrome'.
We figured we would have up to three slots you can add any combination of slots. I call these the cutie mark three.
Some traits we came up with:
1 at-will spell (0th level at level 1, 1st at 5th level, gains a level every 5 levels)
Bonus to movement (+5 feet at first level, 5 additional every 3 levels)
Skill Bonus (+3 skill points to one skill at 1st level, +3 additional points at 7th level and every 7th level after that)
Darkvision (Low light vision 30ft at level 1, 30ft Darkvision at level 7 and plus +30 ft further Darkvision every 7th level after that)
We figured GMs would have to decide whether a feat fits the cutie mark, but are otherwise not allowed. Possible other bonuses could be a bonus to carrying capacity or a small increase to one stat.

Anyway, I am still uncertain as to what I should make the insanities and rules. I want them to both be based off of what options you took, and have it so that the more you rely on your cutie mark powers the higher chance you will go insane and the more it will hurt you.
Currently, I have thought up one rule and two insanities for skill bonuses based off the show:
Rule:
Pride: Character cannot fail this skill check 5 times. Every time the skill's bonus boosts in rank the number that they cannot fail is reduced by one (minimum of 0). After they have their insanity they start the count over.
Inanities:
If At First You Don't Succeed: You can only use that skill (none others) until you succeed. You must use it at every opportunity.
A New Approach: You cannot use that skill at all until you succeed using another skill. You must use it at every opportunity that you would use the special skill.
I was also thinking of possibly having one of the insanities for movement be:
Rainbow Crash: Movement of type increased goes to 0 ft. If you are flying, you start falling to the ground.

As I wanted to make our characters as overpowered as the mane cast, we are starting at level 30. Here are some of the cutie mark options the characters are taking:
Crystal Wishes (Unicorn, 20 Celestial Sorcerer, 10 Eldritch Godling): Cutie Mark: gem signifying magic item smithing; powers: (+15 to Spellcraft, Telekinesis, Teleport (Altilier series))
Speed Chaser (Pegasus, 20 Monk, 10 Time Thief) : (+50 movement, haste, expeditious retreat)
Artifact (Earth Pony, 20 Bard: Archaeologist, 10 Pathfinder Delver): Cutie Mark: Stone Shape, Craft Sculpture, Darkvision 120 ft)
As well we have 6 other characters.

We also added some rules for Equestria based on devalued gems, overvalued apples, and which languages there are.
Gems are much cheaper because they are easily found and dragon food. So all gems are 1/1000 the regular price. Spell components are the same size, just cost 1/1000 the prize. In this way, any magical items that have spells that use gems as spell components are cheaper in this aspect as well. Apples are 10 times the regular price, and meat are forbidden as everyone gems, stones, or plants.
Languages: Due to lack of humanoids met in the world (besides the Derples http://tgchan.org/kusaba/graveyard/res/248137.html ) languages will be taken from The Noble Wild book with some languages from the regular list as well. Languages not in the Noble Wild book that are included: Abyssal, Aklo, Aquan, Auran, Celestial, Draconic, Druidic (druids only still), Ignan, Infernal, Sylvan and Terran as well as Derp and British Equine will be included. If you know of any others that may have been included in the show, tell me.

Please give advice on what the rules and insanities should be in order to balance it, and opinions on the rules I have so far.

Disclaimer:I checked, but couldn't find anything about month old thread necromancy - I hope it's not against the rules (perhaps it is an unspoken taboo? *hopes not*) if not, someone /please/ inform me.
-----------------

I wanted to say that I find your idea of having them as insanities very interesting... But I wanted to suggest that perhaps you consider taking this on a different path...

Have you looked into pathfinder 'traits' much?
Personally I'd probably have a cutie mark be about equivalent to those - providing an affinity, and perhaps bonuses regarding that (action/skill/hobby/setting/emotion/talent/creature/object - et cetera) - or perhaps you could even make them worth a few traits (a standard starting character can have 2 traits, so that would be in keeping with what other pathfinder characters can have - so you could go for that, or even 3, maybe? Before you'd have to effect 'balancing measures')
I was thinking especially of something like the 'harrowed' trait, (if I'm remembering correctly) that has to do with a birth mark, and destiny - this can be a mostly story driven element (if your GM has the patience/actually writes stories.)
You could also consider allowing these bonuses to increase with your level (perhaps at the rate of feats? I don't know... I haven't really thought this out /very/ thoroughly.)

Anyways, it's just a suggestion; some food for thought maybe. :)

(And as for the languages, I think you should consider adding an ancient language that could have been spoken when chaos reigned, or perhaps even before he reigned - but that's my only real ponfied suggestion.)
