The Assassin: The Sanguinity Hot Technique Tree

This supplement introduces a sanguinity technique tree for the Assassin base class, centered on inflicting bleed damage and using enemies’ blood to sustain the character and support allies. The tree includes a blood pool that replenishes as bleed damage is dealt, powering area effects, temporary hit points, healing, and other abilities. It contains 15 new techniques, a blood pool autogrant ability, and three feats for characters specializing in the tree.
