Reaver

Bleeding from her earlier wounds, a human swings her greatsword, cleaving a Minotaur in half. The remaining horde halts as her screams of torment and anguish echo throughout the forest.

As the elaborate coronation carries on, a well dressed Halfling inquires about recent events, knowing when her adversary attempts to lie to her. No weapons are allowed, but she readies a hidden one that appears from her own blood and sinew.

Traversing the battlefield, staff in hand, the elf lifts his hand and casts a devastating spell. Sapping the life force from his foes, they turn to dust before his power.

Reavers are obsessed with gaining power, consuming their enemies flesh or soul. Using their bodies to transform themselves into a higher being. Reavers don't worship gods or otherworldly entities, instead they lust for the power

Secrets and Exploration

Not every Reaver is openly deranged and obsessive. Many, prefer to even hold positions of power, be that government or socially. High authority is usually the perfect place for corruption and consumption. Moving about without scrutiny or question. However there are less fortunate individuals must find other ways to gain power, without causing too much noise in the meantime.

When a Reaver takes up the life of an adventurer their lust for power is lessened by the constant battle and discovery of lost treasures. Pursuing their goals can be a major challenge, and dangerous one at that. Beyond the walls of civilization are countless horrors, ancient tombs, and great evils. All are possible avenues for power and prestige.

Dark Hunger

The Reaver, at some point in their life, begun a dark path of craving power. Perhaps they stumbled upon the rotting carcass of a long dead god or titan. Meditated so deeply, or explored a transient plane too far, and peered into the void. Or possibly in an attempt to bargain for power as a warlock does, the Reaver contacted the dead god Tharizdun, or some other crazed deity, and was driven mad. No matter what the reaver will do anything for the power they crave.

Commoners and scholars will never truly understand where real power comes from. But those that follow the path of the reaver do, it comes from within. To gain such power a Reaver will do anything, eat the flesh of the powerful, siphon lingering magics from people and places, or even fuse your own life with that of a created monstrosity to artificially ascend. No matter how a reaver decides to raise themselves one thing always remains the same, power at any cost. You are driven by blood.

Bloodrage

Starting from when you choose this subclass at 3rd level, while you are at or below half your hit point maximum, you gain a bonus to your weapons' damage rolls equal to your proficiency bonus.

Injured Animal

Starting from 7th level, when you are targeted by an attack that reduces you to half your hit point maximum or lower, you can use your reaction to make one melee attack against the attacker.

Avatar of Pain

Starting when you choose this path at 3rd level, you can channel extreme bloodlust whilst raging which assaults the minds of your quarry. If you choose to do so, you emit a dim red light up to 10 feet while raging. Any hostile creature which enters this area for the first time on a turn or starts its turn there takes psychic damage equal to 1d4 + half your barbarian level.

You are also no stranger to pain yourself, drawing on it to fuel your bloodsoaked frenzies. When your current hit point total is one quarter your maximum hit points or lower, your damage rolls with melee weapon attacks which use Strength can have their Strength modifier doubled. This lasts for one minute and may only be used an amount of times equal to your Constitution modifier + 1 (minimum of 1). You regain all expended uses once you finish a long rest.

Additionally, you can launch attacks driven by pain, ripping into foes while your wounds deepen. When you make a melee weapon attack, you can grant advantage on it in exchange for psychic damage equivalent to your Rage Damage Bonus, as shown in the Barbarian table.

Fueled by Death

Starting from 15th level, you can sustain yourself on the suffering of your enemies. While at or below half your hit point maximum, when you score a critical hit with a melee weapon or reduce a creature to 0 hit points with a melee weapon, you gain temporary hit points equal to 1d10 + your Constitution modifier.

Bloody Slaughter
