Bloodbow is a rare drop from the Chaotic demon Sangus. This bow has the same stats as a Dark bow and requires a Ranged level of 70 to wield. What is unique in it is its special ability. You are healed X% of the damage you inflict (rounded down), with X being the amount of life points you are missing. The special attack energy used up is equal to the percentage you are missing to full health. For example. if you have 243/780 (about 31%, 69% missing) health and you hit 185, you will be healed for 69% from the 185, so you will be healed for 127 LP using 69% of the special attack energy.
