Blood Knight

Some fighters are not satisfied with the conventional ways of combat. They seek to push their limits and test their endurance, using their own blood as a source of power. These fighters are known as blood knights, and they are feared and respected for their reckless and ruthless fighting style.

Blood knights have learned to channel their life force into their weapons and their bodies, enhancing their abilities and inflicting terrible wounds on their enemies. However, this comes at a cost, as they must sacrifice their own health to activate their blood rites. Blood knights are willing to pay this price, as they enjoy the thrill of combat and the challenge of overcoming pain.

Blood knights are often seen as berserkers or fanatics, but they are not mindless or irrational. They are aware of the risks and consequences of their actions, and they have a strong sense of honor and loyalty. They value strength and courage, and they respect those who can match them in battle. They are not afraid of death, but they do not seek it either. They fight for glory, for victory, and for the sheer joy of combat.

Blood knights can be found among any race or culture that values martial prowess and personal challenge. They may serve as mercenaries, soldiers, gladiators, or adventurers, depending on their goals and motivations. Some blood knights follow a code of ethics or a cause that they believe in, while others are more selfish or chaotic. Regardless of their alignment, blood knights are always ready to face any foe that stands in their way.

As a blood knight, you have mastered the art of using your blood as a weapon and a shield. You can coat your weapon with your blood, causing it to deal extra necrotic damage to your enemies. You can also activate a blood rite on yourself, choosing one of three options: blood fury, blood shield, or blood speed. Each option grants you a benefit and a drawback, depending on the situation. You can switch your blood rite as a bonus action, but doing so costs you hit points equal to your fighter level.

As you gain levels, you learn to use your blood for more powerful effects. You can use your blood to fuel your second wind, regaining additional hit points but risking exhaustion. You can unleash a powerful strike with your blood weapon, dealing extra damage and imposing a debilitating effect on your target. You can unleash the full power of your blood when you are wounded, gaining additional benefits from your blood weapon and your blood rite. You can also master the art of using your blood as a weapon and a shield, reducing the hit point cost of your blood rite, avoiding the Constitution saving throw for your blood surge, and enhancing the effects of your blood strike.
