Blood Knight

The Blood Knights are an ancient order of warriors who have mastered the art of manipulating blood to craft weapons and control the flow of life and death. With every strike, they summon weapons forged from their own blood, bleeding their enemies with each blow while harnessing their own injuries to fuel their power.
Their blood carries a generational curse, passed down through a lineage bound to an ancient pact. Twisted by forgotten rites, their very lifeblood has become a conduit for power—potent, volatile, and unrelenting. This inherited curse grants them the ability to shape their own blood into weapons of war, but it also demands a terrible toll, drawing them ever closer to the brink with every drop spilled.
