While in the process of building a Magus character, I got annoyed that paizo decided to make Dex to damage quite difficult to obtain. Apart from Agile weaponry, I know of three feats that do this:
- Dervish Dance is limited to the scimitar, but requires only 1 other feat.
- Slashing Grace works for all light or one-handed slashing weapons, but requires Weapon Focus on top of Weapon Finesse.
- Fencing Grace is similar, but only applies to the Rapier.
Basically, we are looking at at least 2 feats for getting Dex to hit and damage with a limited amount of weapons, which can be a high investment for some characters.
In D&D 5e, Dex to hit and damage is baseline for a similar range of weapons, making me wonder about the implications of making this a house-rule in Pathfinder.
With a light weapon, elven curve blade, rapier, whip, or spiked chain made for a creature of your size category (hereafter finesseable), you may use your Dexterity modifier instead of your Strength modifier on attack rolls and damage rolls.
This bonus is not increased for wielding a weapon in two hands, and you cannot use Power Attack to increase your damage while doing so.
The two restrictions placed on Dex-wielding a weapon are meant to keep Str based characters viable. You can always use Piranha Strike instead of Power Attack, and serve as a counterbalance to Dex contributing to AC and Reflex saves.
Some of the feats could be changed accordingly, such as
You treat one-handed slashing weapons as finesseable.
Does anyone have experience with similar houserules in either Pathfinder or D&D 3.5e (differences should be fairly limited)? Is there some major reason why this is a bad idea to implement?
