Bladebearer of the Valenar( Races of Eberron, p. 107)
Your extensive training makes you especially adept with the curved blades of the Valenar.
Elf, proficiency with scimitar or falchion, region of origin Valenar,
You treat the Valenar double scimitar (see page 119 of the EBERRON Campaign Setting) as a martial weapon, and you gain a +1 bonus on damage rolls when making a melee attack with a scimitar, falchion, or Valenar double scimitar while mounted. If you have any of the following feats for the scimitar, falchion, or Valenar double scimitar, you can apply the feats' effects to all three weapons: Improved Critical, Weapon Focus, Weapon Specialization, Greater Weapon Focus, or Greater Weapon Specialization. Additionally, when you spend an action point to influence an attack roll made with either a scimitar, falchion, or Valenar double scimitar, you also add the result of the action point roll to your damage for that attack.
