Dex to damage with a rapier

[elgabalawi]

So there's feat ways to get decided to damage for slashing weapons (dervish dance, slashing grace), but I can't find one for an actual piercing weapon. Anyone have any insight on this? It doesn't have to be a feat, just want dex to damage on a rapier without buying the agile property.
Thanks in advance

Fencing Grace, or 3 levels in unchained rogue.

Fencing Grace.

Generally speaking, if you use your rapier well enough there'll be plenty of red to damage. Mostly organs.

Awesome. Thanks so much
