The bot always clicks the last crystal in the inventory. I think this is likely an identifiable pattern. When I do the minigame legitimately, I click a random crystal because I don't sit on the client and watch the crystals transmute; I open other windows since the empowered crate usually lasts about 40 seconds before changing. Also, maybe add a checkbox option in the interface to take a short but randomly determined amount of time before switching to the new active crystal – It's so quick to identify the next empowered crystal to work on that it doesn't seem human-like.
