Combat Overhaul

Upon taking this feat, you can use a Reaction against an attack to make one of the following combat maneuvers:

Parry. As a reaction against a melee or ranged attack, you can make an attack roll against the attacker's attack roll. Triggering the effects below:

• Successful Parry. When you roll above a DC equal to half but lower than the attacker, you take half damage from the attack. You are pushed back 5 ft. from the attacker. 
• Perfect Parry. Whenever your roll matches or exceeds that of your attacker. You negate the damage from the attack and can make a free attack against them. You roll this attack with advantage.
• En Garde! Upon triggering a Successful Parry or Perfect Parry, you regain your reaction, allowing you to parry again or to perform another reaction action.

Dodge. As a reaction against an attack or spell save that deals AoE damage, you can make a Dexterity saving throw to disengage and move up to 10 feet:

• Successful Dodge. You take no damage and can disengage up to 10 feet.
• Failed Dodge. You take half damage from the triggering attack and are able to move up to 10 feet away without opportunity attacks.
• Dark Souls. Wearing Medium or Heavy armor only allows you to move up to 5 feet with this feature. You can Dodge a number of times equal to your Dexterity Modifier until you take a short rest.

Block. As a reaction, you raise your weapon, shield, or limb against the triggering attack. You gain temp hp equal to the sum of your highest hit die (1 die) + AC + Constitution Modifier. Lasting until the end of your next turn.
