Fighting Style Feat (Prerequisite: strength 15 or higher)

When you make an extra attack as a result of using two weapons, you can add your ability modifier to the damage of that attack if you aren’t already adding it to the damage.

you can weld a separate melee weapon in each hand that is 8 pounds or lighter and not two handed

when wielding the same type of weapon in each hand (example: one battleaxe in each hand) you can add +1 to your damage result 

 if you are wielding versatile weapons the damage is its one handed output
