Twinned Weapon Master

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

• You can make two attacks instead of one with your bonus action from two-weapon fighting, but only when you use a melee weapon and if you do not use the weapon for other attacks this turn. All other conditions from two weapon-fighting still apply.
• When you hit a creature with an oppertunity attack, you can make a secon attack against it using two-weapon fighting as part of the same reaction, but only when you use a melee weapon.
