Someone just taught me this and well I thought it was good.
Basicly the aim of this is to get them murderer so when you kill the bot you get some stuff hopefully and a bot dead.
What you do is Attack one with your hands or frost nova etc Just to make them aware of you. Now if you are lucky and youve got a good bot then it will attack back. [NOTE] ONLY SOME BOTS WILL ATTACK BACK. This is your cue to run away and wait for your pink to dissapear but make sure you dont lose the bot and it gets distracted by a mob. Ether way as soon as you go white jump on your horse.
The bot will kill your horse and get murderer meaning you can kill it

. I have retrieved gold bots bows meaning they have been punching demon horses and I have also got some +3 weapons and armor 6d etc.
A great place to practice is the demon horses, the archer bots there normally attack back.
This is just a fun activity to do and get some free stuff,
Any questions please ask and remember just because a gold bot is attacking the mob doesnt mean it is your level .. So try not to attack it then get one shotted by a fiery ball of hell.
