Invisible fighter

You are in your natural element when you are magically or naturally invisible. As such when you fight in this state you know the perfect way to utilize the ability. You gain the following benefits:

• when you are invisible you do not make any sounds with your feet or equipment unless you are wearing armor that imposes disadvantage on stealth.
• when you attack a creature and hit with any melee weapons you deal an extra 2d6 damage.
• on a crit or bring a creature to 0 hit points you can make another attack as a bonus action.
