Spell / feat similar to Gravity Bow for non Rangers?

[sjsobota]

I was trying to help increase damage on my two weapon wielding paladin, and since I am not able to use a 1 handed non light weapon in my second hand without the penalty (see post on 1 handed question, GM won't allow 3.5 rules), I was looking to find a way to increase the damage.

In 3.5 there was a similar spell to Gravity bow in the Races of Stone book called Earth Hammer (p. 162) that increases the category of 1 weapon in size increment (for purposes of damage). As my GM won't allow for 3.5 rules, is there something similar a dwarf paladin could use, either in feat, or some 3rd party Pathfinder compatible supplement?

Thanks,

Jim

Mostly, Smite Evil and Divine Bond (enhance weapon) are there to help a paladin increase their damage dealing. Also note that bless weapon, divine favor, bull's strength, weapon of awe (APG), greater magic weapon, fire of vengeance (APG), resounding blow (APG), and holy sword are on the paladin's spell list. In addition, a paladin can use the variant channeling rules in Ultimate Magic (once the Channel Positive Energy ability is gained at 4th level) and/or take the Alignment Channel, Channel Smite, and/or Elemental Channel feats (to increase damage against specific types of foes).

Honestly, if you hare having problems dealing damage with a twf paladin, you have some pretty high standards. But you have a high charisma, presumably. How about a want of Lead Blades (ranger spell like gravity bow but for melee) and UMD? Use that when you're not smiting.
