Annoying bots AND making money!

You could drop one green dragonhide, wait for them all to swarm, and then freeze 2 or 3 of them with barrage spells, then keep hitting them with the spells. Faster kills imo.

Killing karumja fishing bots was the respective moneymaking mathod for F2Pers.
Not many knew of this method as it was sort - lived. The main idea was to lure the scorpion close to stiles so he could kill the low level bots, then the one who lead the scorpion would go over the grave to pick their noted fish. Bot users learned that and they started training their bots to combat level 49 which the scorpion stops being aggressive.
Anyway it was very profitable as it wasn't very competitive (not many people knew about that)
and the bots had very valuable drops(i have even heard for drops as high as 5m!)

There was a trick to skull bots so you can keep their whips! I think it still works with the LOLcano emote
