So a DM friend of mine wanted all classes to be able to cast spells without needing the take levels in a spell casting class. He posted this to reddit, but he did not get very helpful feedback, and since he does not have a paizo account (and does not really want to make one), I am posting this in his place.
Sorry for the weird formatting, and thank you all for your feedback
• Anima points
o Can be gained instead of a favorite class point on level up
o These points can be used to increase your vim pool
• At 1:1 ratio
o Or to buy new spells known
• Spells cost 1 point per spell level.
• You must know 1 spell from every level before you can take one from a higher level
• You must have an ability score equal to 10+ the level of the spell to learn a spell
o Your caster level for your vim powers is equal to your max vim pool
• Casters levels do not stack, you use your highest for all your spells between your normal class caster level or your vim caster level
• Vim points
o You only gain a vim pool if you buy one with anima points
o Are expended immediately upon casting a spell
o Regain after 8 hours of rest.
o You gain bonus vim points based on your vim casting ability score. The number of bonus points you get each day is equal to the highest level of bonus spell you would be able to get tied to your casting ability score.
• Casting
o When using vim points, you cast as a level 1 caster of the spell list you chose
• This is for armor, and arcane spell failure chance.
o The first time you get an anima point, you must choose a mental ability score that is not already in use for casting, and you will now use that ability score to cast spells with vim points.
• You may cast spells by taking ability point damage to this ability score equal to the vim point cost of the spell instead of expending vim points.
Some Extra feats
Powerful Spirit
• No Prereq
• Acts as toughness but for Anima Points
Boundless Spirit
• Prerequisite: Powerul Spirit
• Permanent +3 Anima points
Physical Caster
• Prerequisite: 1 Anima Point
• You may use one of your physical ability scores to determine if you are able to learn a spell or not. As well, you can use this ability score to cast spells instead of your mental ability score. Your mental ability score still determines the save DC for your vim spells.
o Int Casters use Str
o Cha casters use Con
o Wis casters use Dex
Will be adding more feats later.
