Dual Sword Master

You master fighting with two one handed sword weapons (longsword, shortsword or scimitar) gaining the following benefits:

• You can use two-weapon fighting even when the one-handed melee weapons you are wielding aren't light.
• Your critical hits with one-handed sword weapons ignore "resistance to slashing damage" and "immunity to slashing damage" is reduced to "resistance to slashing damage".
• Each time you roll a critical hit with each of your one-handed sword weapons (while in dual wielding), you can add one additional damage die of the weapons type.
