Sources of Bonus':
- Spells (from any casting source)
- Equipment (such as from Fine Quality weapons)
- Ally (such as the "Assist Ally" action)
- Talent (such as Weapon Mastery T.1)
- Magic Item (such as Runes)
- Racial (such as the Kelekene bonus to "Wild Assault")
- Skill Ranks (not so much of a 'bonus', but a trained ability)
- Path (listed in the Errata, but can't think of an example off the top of my head)
- Combat Maneuver (such as the +5 to damage from Mighty Swing)
- "Untyped"
I don't think this is totally correct, per the clarification of the stacking bonus on page 12 of the errata. There it spells out that "Ally" includes spells and talents from allies, so you could have one spell boosting your attack bonus that you cast, and one that an ally cast, and they would add - but there is a caveat that you can't have the same spell effect you twice (like benediction of the gods cast by you and an ally). It makes Ally a pretty broad palet. It's nice because it means that if they have a talent or spell, it will probably help you out, but it means that if one has a talent, and one has a spell, that do the same thing for allies - they won't stack.
