Gory Finish

Prerequisite: Great Weapon Combat Style

By drawing upon wells of savagery, you can slay your foe in creative and horrifyingly gruesome manners, intimidating nearby foes. Once per round, when you make a melee attack that reduces a creature to 0 hit points, you can try to demoralize all foes within 15 feet and who could see your attack as part of your action. Make a Charisma (Intimidation) check (DC for each creature is set at the GM's discretion). On a successful check, the enemy becomes demoralized by you and takes a -2 to all attack rolls, saving throws, and ability checks until the end of your next turn.
