IM looking for a way to make my Sorc claw attack at least on par with other melee weapons, I will have a 16 starting strength to that helps. Also only using the Core book.
Also will be looking for ways to improve them as I lvl.Please help.
If you are just using the CRB, all you have is size modifiers (Enlarge spells). There is the improved natural attack feat from the Bestiary, but that isn't the CRB.
Well, Dragon Disciple is one of the best solutions, gives you stuff and +str on the side. One of those +str belts is good too, the one that makes your weapons one size bigger when charging.
Amulet of Mighty fists with Wounding would apply a bleed effect with every slash.
Sorcerer's have high Charisma and can use UMD to cast Magic Fang trough wands or scrolls, though it's just +1, which a 4,000gp amulet of mighty fists duplicates.
It really depends what level and wealth OP has access to.
