This lets you have a sword on fire when it's not supposed to be. You need the bloodfire cutlass ( famed ), see the weapon card, or any other sword with the blood fire ability. You also need another sword, whatever one equipped. Step 1: Take the bloodfire sword out. Step 2: Kill an enemy with the sword, so that the blood fire ability turns on, and that your sword is on fire. Step 3: Switch to the other sword you have equipped by clicking on it. Step 4: The sword should be on fire! It stays so until you put that weapon away.
