Bloodstone Tipped Arrows
This is an arrow with the arrowhead made of Bloodstone. Bloodstone seeks and absorbs blood, one of the things it does it extend tendrils upon contact with a warm body. When the arrowhead makes contact with a warm blood filled body it extends tendrils into the body of the victim. Each round it does 1D damage to the victim max of 5d6. Short of surgery it is not possible to remove the arrowhead. Working with Bloodstone arrowheads can be dangerous, a roll of 100 while using bowyer/fletcher to make arrrows causes the crafter to take 2d6 damage, 1 going in and 1 coming out from the tendrils assuming they have a safe way to withdraw the arrowhead from their body.
