# Does 2 handed multiplier apply to Dex mod with Weapon Finesse?

I have a rogue with Weapon Finesse.

This allows me to:

When making a melee attack with a light weapon or rapier, you may use your DEX Mod instead of your strength Mod on the attack roll.

Since a rapier's hands datum is 1, I can wield it two-handed and

In the case of STR=1,DEX=3 with Weapon finesse, is a 2 handed attack always +1.5, or can it be +4.5?

@mxyzplk has a point on DandDwiki (hence this is a comment and not an answer), but if your DM will allow a weapon enchantment to be imported your dex could apply with 2-h dandwiki.com/wiki/Graceful_Striking_(3.5e_Equipment) – LitheOhm Sep 21 '12 at 18:47
What if the weapon is keen and light? – Julix May 22 '13 at 20:45

No, for three reasons:

First, Rapier specifically states:

You can’t wield a rapier in two hands in order to apply 1½ times your Strength bonus to damage.

Second, Weapon Finesse allows you to use DEX mod instead of STR mod on attack rolls. Wielding a one handed weapon in two hands allows you to add to your damage rolls. Two completely different cases.

Third, you cannot use Weapon Finesse when wielding two handed weapons, or wielding a one handed weapon in two hands. There are a couple of specific items that change this ( iirc, Elven Courtblade from Races of the Wild and the cheesechain Spiked Chain ), but it is limited to those items.

Where does it specifically say that you cannot use Weapon Finesse when wielding two handed weapons? – Macona Aug 2 '12 at 7:50
@Macona "with a light weapon or rapier" Neither of these can be 2 handed. – StuperUser Aug 2 '12 at 9:07
@Macona - StuperUser has it right dandwiki.com/wiki/SRD:Light_Weapon : "Using two hands to wield a light weapon gives no advantage on damage; the Strength bonus applies as though the weapon were held in the wielder’s primary hand only." – Phill.Zitt Aug 2 '12 at 15:47
Ok, but the Spiked Chain and the Aldori Dueling sword are not light weapons, so they can be finessed with two hands. – Macona Aug 3 '12 at 8:32
Dandwiki is NOT valid for Pathfinder - use d20pfsrd.com or it's irrelevant... – mxyzplk Aug 6 '12 at 15:15
