Does Weapon Finesse allow you to use Dex instead of Str on a CMB check if used with a light weapon?

[RigaMortus]

This is why I think Weapon Finesse applies Dex instead of Str for CMB.

CMB = Base attack bonus + Strength modifier + special size modifier

Performing a combat maneuver: When you attempt to perform a combat maneuver, make an attack roll and add your CMB in place of your normal attack bonus.

Weapon Finesse: you may use your Dexterity modifier instead of your Strength modifier on attack rolls.

[williamoak]

YES! For any finesse weapon.

[TGMaxMaxer]

So long as it's one of the maneuvers that use weapons, not all do.

[Imbicatus]

Only on weapon based maneuvers, which by default is Trip, Disarm, and Sunder.

There's a FAQ for that:

Weapon Finesse: If I have this feat, can I apply my Dex bonus to my combat maneuver checks instead of my Strength bonus?

It depends on what combat maneuver you're attempting. Disarm, sunder, and trip are normally the only kinds of combat maneuvers in which you’re actually using a weapon to perform the maneuver, and therefore the weapon’s bonuses apply to the roll. Therefore, if you're attempting a disarm, sunder, or trip maneuver, you can apply your Dex bonus instead of your Str mod on the combat maneuver check (assuming you're using a finessable weapon, of course). For other combat maneuvers, you use the normal rule for determining CMB (Str instead of Dex).

The Agile Maneuvers feat applies to all combat maneuvers, not just disarm, sunder, and trip, so it is still a useful option for a Dex-based creature that uses combat maneuvers.

So, can you stack the +Dex from Weapon Finesse, Agile Maneuvers, and Fury's Fall on a Trip Combat Maneuver?

[blackbloodtroll]

Fury's Fall, yes. Agile Maneuvers, no.

[Imbicatus]

Weapon Finesse and Agile Maneuvers both allow you to substitute Dex for STR, so they do not stack. However, Fury's Fall allows you to add dex in addition to STR on Trip maneuvers. If you had Weapon Finesse or Agile Maneuvers, you could add double your Dex with Fury's Fall since you are substituting dex for str from finesse/agile, and adding dex from FF.

Thus begins another Fury's Fall thread.
