Flinches Cerberus. Uses no food and no prayer points!
Set your quick prayers to whatever you want the bot to use and start the bot in one of the rooms. If there are flames blocking the path between you and Cerberus, pause the bot and pass them to start the process.
This bot does not bank! I recommend bringing runes for High level alchemy and at least 6 Super combat potions for long trips.
The bot will move to a safe location, log out and stop when your task has been completed or when your inventory is full.
