The only way to crusade in style: Here's a fully automated bot for CotLI! This bot will buy you new levels (with or without upgrades), click the enemies, use the built-in free buffs and keep pushing forward to new areas. Meanwhile, people like you and me can participate in the so-called "real life".
Note that this extension comes with a native Windows .Net program, which is required in order to send mouse clicks to the flash game window. (Full source code included for those with a CRX viewer.)
