CBoy is a small, easy to use clickbot.
It can be used to auto-attack as a caster, anti-afk, and even anti-afk in WoW. However, it was designed to be a quick, simple bot for AoC Casters.
Tried it on my necromancer, and it worked like a charm.
It's only 18 KB in size, and if you wish to try it, open up notepad, activate the bot, and watch for yourself.
