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
If you wield it two-handed, add 1-1/2 times your STR Mod to melee damage instead.
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?
