Hi, fellow pathfinders!
I've just create this two feat. It's an alternative to Dervish Dance. Please criticize my work ( and please understand that I'm not english, not a grammar nazi ;) )
Accurate WeaponPrerequisites: Dexterity 13, Weapon Finesse, Sleight of hand 2 ranks, proficient with selected weapon.
Benefit: Choose a weapon. This weapon must be finessable or any one handed weapon. When wielding such weapon, you can use your Dexterity modifier instead of your Strength modifier on melee attack and damage rolls. You treat your dexterity modifier as strength modifier for all feat, class abilities and so on ( for example, if this weapon is a two handed weapon with finesse special feature,like a spiked chain or elven curve blade, you can apply 1-1/2 your dexterity modifier on damage rolls ) You cannot use this feat if you are carrying a weapon or shield in your off hand ( except two handed finessable weapons )
Accurate Weapon, ImprovedPrerequisites: Dexterity 13, Weapon Finesse, Accurate Weapon, Sleight of hand 7 ranks, Weapon Focus ( any ).
Benefit: When you use your accurate weapon feat with a weapon in wich you have weapon focus, you gain a +1 shield bonus, plus any enhancement bonus your weapon has. Moreover, you can apply feat that improve your shield bonus to armor class ( for example: Shield Focus ) to improve this shield bonus. Same limitations of Accurate Weapon applies.
