You master fighting with two finesse melee weapons, gaining the following benefits when wielding two weapons:

• You gain an additional +1 bonus to AC while you are wielding a separate melee weapon in each hand. 
• You can draw or stow two one-handed weapons when you would normally be able to draw or stow only one.
• Once per turn you can choose one of the following:
  1. You may attempt to use the off-hand weapon to gain Advantage for your primary weapon by expertly performing a fight combo for one attack or reaction. Roll a Strength (Athletics) or Dexterity (Acrobatics) check (DC16) to succeed. Then roll for your attack.
     
  2. You may roll an attack for your off-hand weapon during 1 normal attack action or reaction, and add the damage of a successful hit without proficiency or attack modifier bonuses.
  3. On a Dodge action you may roll your off-hand weapon damage dice, and add half of that roll (rounded down, a one would be +0) to your AC until your next turn.
• this feat does not use a bonus action, and you may attack with your off-hand weapon if available. (This assumes a bonus attack would precede a Dodge Action)
