Light Weapon Master

You’ve learned to use the lightness of a weapon to your advantage, letting it's swiftness empower your strikes. You gain the following benefits:

• On your turn, when you score a critical hit with a melee weapon that lacks the heavy property or reduce a creature to 0 hit points with one, you can move your full speed and make one melee weapon attack as a bonus action.

• Before you make a melee attack with a melee weapon that lacks the heavy property, you can choose to take a -5 penalty to the attack roll. If the attack hits, you may make another attack as a free action, the free attack can not trigger this ability.
