This is a retool of my previous "Martial Spirit" bloodline: http://paizo.com/paizo/messageboards/paizoPublishing/pathfinder/pathfinderR PG/communityContent/houseRules/archives/sorcererMartialSpiritBloodline
It's been refluffed and rebalanced!
-------------------------------------------
Legendary bloodline
There was either a mythic warrior of great prowess in your family tree, or perhaps you are the latest born to a long line of such heroes. For some reason or another, the spirits of your ancestors have chosen you as their successor, and somehow lend you their legendary skill and power from beyond the veil of death, giving you supernatural abilities.

True Strike (3rd)

Skill Focus (Knowledge: History)
Bloodline Arcana: You may deliver a melee touch spell through a single attack with a melee weapon. A spell cast in this way uses its standard casting time and you may make your attack as part of the casting - but you may not take a full attack action when delivering a spell in this way, and you provoke attacks of opportunity as normal when casting in melee. You declare use of this ability as well as which spell you are casting before making your attack roll. The spell takes effect even if the target's damage reduction negates the damage dealt, but you must land a successful hit.
Bloodline Powers: Guided by the souls of your ancestors, your weapons strike true and your enemies become humbled by your prowess.
Legendary Strike (Su): As an attack action, you may make an attack with a manufactured weapon and add half your Sorcerer level to the damage dealt. You may use this ability a number of times equal to 3 + your Charisma modifier.
Watchful Protectors (Su): At 3rd level, you gain a +1 deflection bonus to your AC. At 9th level, this bonus increases to +3, and at 15th level, this bonus increases to +5.
Memory of Prowess (Su): At 9th level, when making attacks with a physical weapon, you may treat your character level as your base attack bonus for a number of rounds per day equal to your sorcerer level (which may give you multiple attacks). These rounds need not be consecutive. Using this ability is a free action.
Mythic Grace (Ex): At 15th level, you gain +15 feet to your base land speed and gain a +6 dodge bonus against attacks of opportunity provoked by moving through a threatened square. You also gain a +3 dodge bonus against attacks of opportunity made for any other reason.
True Successor (Ex): At 20th level, you have achieved legendary greatness equal to or surpassing that of your ancestors. When delivering a touch spell through a single melee attack (via your Bloodline Arcana), the spell automatically ignores the target's spell resistance. You also gain a +4 inherent bonus to your Strength and Dexterity, and all of your Bloodline Powers become Extraordinary Abilities.
-------------------------------------------
Changes:
The fluff has changed - the power source is no longer implied to be explicitly non-magical. Perhaps this legendary hero you're descended from was an Eldritch Knight, or your ancestors were mages as well as warriors.
Legendary Strike was toned down significantly. Instead of giving a bonus to any attack roll, it instead lets you make an attack action with a weapon and add to your damage.
Watchful Protectors gives a Deflection bonus instead of a Competence bonus, and therefore stacks with fewer things.
Mythic Grace's AC bonus against AoOs was toned down by 25%.
Opinions? Is it better? Worse?
That's starting to look a lot better; memory of prowess is more appropriate for a bloodline than revamping the entire class' BAB.
One thing to notice is that the bloodline feats list always includes one metamagic feat, one save bonus feat (Iron Will, etc.), and one Skill Focus feat. The remaining five you can pick and choose.
I really like this bloodline aside from some minor tweaks I'd make to the feats (as outlined by Kirth above) and bonus spells. The meat of it looks really good though.
As to my bonus spells comment I don't see how Crushing Despair, Protection from Spells, or Astral Projection really fit (well maybe Astral Projection but it feels like a stretch). Also keep in mind that you can pull from other classes spell lists for those bonus spells, the celestial bloodline set that precedent, and some of the bonus spells can be late or early entry as well.
As to some alternative spell ideas for this concept.
Speak with Dead instead of Crushing Despair.
Gate instead of Astral Projection (but only to the plane on which your ancestors spirit resides, if used as a calling effect can only be used to call your ancestors). I think you wanted a spirit world thing with Astral Projection but this isn't how D and D cosmology works. Gate is how you go visit the dead.
Protection from Spells could be replaced with Moment of Prescience which has precedent in the Bloodline Powers anyhow.
Ah, those are some very good suggestions, both of you - I'll prolly incorporate them into my next build of this bloodline (which will hopefully be the last one)
I think Still Spell for the Metamagic, and Great Fortitude for the saving throw would work - Still Spell to avoid ASF when it really counts, and Great Fortitude to make up for a Sorcerer's usually lackluster Fort. save.
I think Foresight instead of Gate might work better, though - since Gate would need a lot of limitations to keep it in theme.
I have some other ideas for spells that fit this theme too. Obviously the spell list is only so big though but if you are open to new ideas consider Augury (I know you have contact other plane but Augury is another option) and Planar Ally (any strength of this could work for calling back your ancestors).
