Thanks for the thoughts, SB.
Talent is an isolated feat - spellcasting will be based on classes rather than a feat system, mostly because I'm not sure how to put one together - but I wanted to have it as a prerequisite for the Witch class. Similarly Faith will be a prereq for the Chosen One and Paladin classes, and I think Druids will need either Faith or Talent (Wise Caster). That's all a bit nebulous thus far, though, because the classes aren't written yet!
Ideally, I'd like to make this most appealing to those who are aiming for the Witch or Druid class, and less appealing to warrior, sneaky or social types. The intention is that it's not necessarily something that's very useful on its own - it's a minor bit of inborn magical ability - but without that raw talent, becoming a spellcaster at all is absolutely impossible.
I'm still not 100% sure about this route either, but it'll at least be interesting to see where it takes us.
Let's see, then, how about the following rewrite:
TALENT
You have a minor aptitude for magic.
Prerequisite: Int 15+ (Intelligent Caster), Wis 15+ (Wise Caster), or Cha 15+ (Charismatic Caster).
Benefit: You may cast a small amount of magic. Choose one of the following options:
Intelligent Caster. You know one of the following 0-level spells: Detect Magic, Read Magic, Prestidigitation, or Mage Hand. You may cast the spell a number of times per day equal to 3 + your Intelligence modifier. Where applicable, your caster level is equal to your character level.
Wise Caster. You know one of the following 0-level spells: Cure Minor Wounds, Know Direction, Guidance, or Virtue. You may cast the spell a number of times per day equal to 3 + your Wisdom modifier. Where applicable, your caster level is equal to your character level.
Charismatic Caster. You know one of the following 0-level spells: Ghost Sound, Dancing Lights, Daze, or Lullaby. You may cast the spell a number of times per day equal to 3 + your Charisma modifier. Where applicable, your caster level is equal to your character level.
Special: This feat may only be taken at first level.
And possibly the following three feats too, which I'm pretty much making up as I go along:
STUDENT
You are a student of the magical arts.
Prerequisites: Talent (Intelligent Caster), Int 15+
Benefit: Choose one of the following spells: Comprehend Languages, Identify, Hold Portal, or Detect Secret Doors. You may cast this spell a number of times per day equal to 1 + your Intelligence modifier.
ACOLYTE
Your devotion grants you a small measure of power.
Prerequisites: Talent (Wise Caster), Wis 15+
Benefit: Choose one of the following spells: Cure Light Wounds, Bless, Sanctuary, or Command. You may cast this spell a number of times per day equal to 1 + your Wisdom modifier.
ENCHANTER
Your charm is almost supernatural.
Prerequisites: Talent (Charismatic Caster), Cha 15+
Benefit: Choose one of the following spells: Charm Person, Unseen Servant, Hypnotism, or Sleep. You may cast this spell a number of times per day equal to 1 + your Charisma modifier.
