So it has been on my mind lately, What are the ways for a character to convert Dex into Damage. For this let's stick to official Pathfinder products:
A few that I know of:
Feats:
* Slashing Grace (Slashing Weapon of choice/interacts weirdly with Weapon Finesse)
* Fencing Grace (Rapier Only)
* Dervish Dance (Similar issues to Slashing Grace, Scimitar only)
Class Ability
* Unchained Rogue @ Level 4 (IIRC)
Archtypes:
* Swashbuckler: Whirling Dervish @ level 4
Prestige Class
* Aldori Swordlord @lvl1 (Aldori Dueling Sword only)
I know there are others...what you got for me?
There is a feat intensive combination by which fighters can get Dex to damage on some fighter weapon groups. By combining Martial Versatility with the Spear Dancing Style feats (Nodachis are in two weapon groups) and then multiclassing to Rogue for 3 levels you can get dex to damage on your finessable Spear Dancing weapons.
Another feat: Starry Grace (Star Knives)
The agile magic weapon property.
Mythic weapon finesse.
