Master Dual Wielder

You master fighting with two weapons, gaining the following benefits:

• Weapon Flurry: Instead of attacking with your off-hand weapon as a bonus action. You can now add the off-hand weapon to your primary attack using the same attack roll and add its damage die and damage modifier of the off-hand weapon (Str or Dex) with the damage of the primary weapon.
• Weapon Combo: You gain +1 to hit when dual-wielding two different weapons damage types. (ie: slash/bludgeoning, piercing/slashing, etc etc.)   
• You can now add your combined weapon damage proficiency modifier to any charisma base skill or check when both weapons are drawn at the ready.
