Blood Damage is a prefix that turns up on Head and Relic. It gives Blood Damage: +3% to +5% at its lowest step, +67% to +91% at its best — and you need item level 116 before the best one can appear at all.
It comes up at weight 4 when the game rolls affixes, never doubles up with another affix that does the same job (affinity_damage), and it is what puts Scarlet, Wounding, Gushing, Vermilion and Butchering in an item's name — so you might pick up a Scarlet Wand.
No Unique carries it at a fixed number.
