Reaver

Brazen and brutal in equal measures, the Reavers charges headlong into the thick of battle. The more enemies that stand in a reaver's way, the bolder their strikes and the harder their enemies fall. Reavers chase the thrill of combat, and when they find it, hordes of foes break upon their maelstrom of steel.

Lord of the Fray

Starting at 3rd level, the ferocity with which you attack groups of foes empowers your strikes. When you hit a creature with a melee attack, you gain a bonus to the damage roll equal to the number of hostile creatures within your reach.

Cornered Fury

Starting at 3rd level, you know how to fight back against being cornered. When a creature misses you with an attack roll, you may use your reaction to deal bludgeoning, piercing, or slashing damage (determined by your equipment) equal to your Fighter level to each creature of your choice within 5 feet. You can use this feature a number of times equal to your proficiency bonus.

Battlestride

Starting at 7th level, your movement speed increases by 10 feet, and you can move through the spaces of hostile creatures without a penalty to movement. When you move through the space of a hostile creature for the first time on your turn, the creature takes bludgeoning damage equal to your Proficiency bonus.

Merciless

Starting at 10th level, your brutality and ire is unrelenting. When you reduce a creature to 0 hit points on your turn, you gain a 10 foot bonus to your movement speed that turn. If you reduce 2 or more creatures to 0 hit points on your turn, each creature of your choice within 30 feet that can see you must make a Wisdom saving throw or be frightened of you for 1 minute.

A frightened creature can repeat the saving throw at the end of each of its turns, ending the effect on a successful save. The DC for the saving throw equals 8 plus your Constitution modifier, plus your Proficiency bonus.

Steelweaver

Starting at 15th level, you learn to channel the chaos of battle into your calculated strikes and dominating presence. When you make an attack roll, you may choose to apply your Lord of the Fray bonus to either the attack or damage roll.

Additionally, you can bolster your resolve against hordes of foes. As a bonus action, you gain a bonus to your Armor Class equal to the number of hostile creatures within 5 feet of you until the start of your next turn. You may use this feature a number of times equal to your Constitution modifier per long rest.

Avatar of Havoc

Starting at 18th level, you have become a destructive force of war, singlehandedly felling hordes of foes and marking your unwavering presence on the battlefield. You are immune to being frightened and have advantage on attack rolls against creatures that are frightened.

As a bonus action, you can enter a state of havoc. For 1 minute, whenever you make a melee attack roll, the number rolled to hit applies to all creatures within your reach. Once you have used this feature, you cannot use it again until after you have finished a long rest.
