You master fighting with two light one-handed weapons, gaining the following benefits:

• 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 if you are wielding two light one-handed weapons you can choose one of the following:
  1. Attempt on an attack action, or reaction, to use the off-hand weapon to gain Advantage for your primary weapon attack by expertly performing a fight combo. Roll a Strength (Athletics) or Dexterity (Acrobatics) check (DC16) to succeed.
     
  2. On an attack action, or reaction, add your off-hand weapon damage to your normal attack without proficiency or attack modifier bonus.
  3. On a Dodge action you may roll your off-hand weapon damage dice, and add that roll to your AC until your next turn
• this feat does not use the bonus action, and you may attack with your off-hand weapon if available. (This assumes a bonus attack would precede a Dodge Action)
