Blood Gems are upgrade materials in Dark Souls III.
- A gem of infused titanite.
Slurped by Irithyll slaves.
- Used in infusion to create lacerating weapons.
- Such weapons inflict lacerating damage.
Most effective with sharp or spiked weapons.
The player must obtain the Profaned Coal and give it to Andre of Astora to allow infusion of this gem into a weapon.
Use the Blood Gem to infuse a weapon with the Bleed effect. The infusion will reduce base physical damage and scaling, while adding or increasing Bleed buildup, which scales with Luck.
- Blood-infused weapons cannot be buffed.
