Two-Handed Weaponmaster (5e Feat)

Prerequisites: Strength 13 or higher
You have mastered the ability to fight with two-handed weapons.

You can cleave through your enemies with your attacks. When an attack with a versatile or two-handed melee weapon you are wielding in two hands reduces a creature to 0 hit points, you can use your bonus action to perform an additional attack with the same weapon.
Your attacks are incredibly hard to block. Whenever a creature uses its reaction to gain a bonus to AC against your weapon attacks with a versatile or two-handed melee weapon you are wielding in two hands, you can use your reaction to negate this bonus.
Your attacks can be felt even through heavy protection. Whenever you miss an attack with a roll of 10 or higher with a versatile or two-handed melee weapon you are wielding in two hands against a creature able to reduce the damage of your attacks or against a creature equipped with heavy armor, you deal damage to that creature damage equal to your Strength modifier.
