Dark bow

The dark bow is currently the most powerful bow in Old School RuneScape. It fires 2 arrows per shot. Its special attack fires 2 arrows with a maximum hit of 30 % higher than usual and a minimum hit of 5 per shot, using any arrows other than dragon (descent of darkness). A special attack using dragon arrows  fire 2 shots with a 50% higher maximum hit than usual and a minimum hit of 8 per shot (descent of dragons). The descent of dragons special attack fires an animation of 2 black dragon heads at the target.

The dark bow may be powerful and accurate, especially with its special attack, but its firing speed is slow. Its speed on rapid mode is the same as a 2-handed sword (3 seconds) just remember that you are shooting two arrows per shot.

The Dark Beast is the only creature known to drop the Dark Bow, it requires level 90 slayer to be killed.
