Improved Great Weapon Master

Requires: feat Great Weapon Master

You've learned to put the weight of a weapon to your advantage, letting its momentum empower your strikes. You gain the following benefits:

• On your turn, when you reduce a creature to 0 hit points, you can apply the overflow damage to another enemy in range if your original attack roll would also beat this enemies ac. You can continue this until your attack runs out of damage.
• Before you make a melee attack with a heavy weapon that you are proficient with, you can choose to take a further -5 penalty to the attack roll. If the attack hits, you add an additional+10 to the attack's damage.
