Scorpion Bow

The Scorpion Bow is an Bow that is unlocked doing Slayer Quests, and requires Spider Slayer III. This bow may seem inferior to the Runaan's Bow if you compare raw stats, but the damage output of the Scorpion Bow's ability is greatly superior to the respective bow. For example, if you have 100, the damage dealt would be 3500 + 110 (damage 220 on a crit) + whatever  you have, potentially dealing tens of thousands of damage. Not to mention that the ability's damage is per second for six seconds. However, with the price of tarantula silk from bazaar as of July 2020, the total cost of this bow sums up to around 3.6 million. Though the ability of this bow is superior, the Mosquito Bow is recommended instead of this.
