Which minigame? I made a bot for mage training arena for all rooms, but the most interesting one was the enchanting chamber: there were dragonstones with a very high, but constant respawn rate that were highly contested. My script jumped through different servers and after finding and collecting one, it remembers the time when it spawns on that particular server. It was very satisfying to watch it run there just few seconds before they spawned, leaving other players no chance.
