There was actually and exploit using the gather epic and farming epic. You could make an xp farm by planting and replanting. All you had to do is gather trumpets , have a portal which is a exit from another planet then have a bunch of trumpets planted and at the end of the planted trumpets have a portal to the other world. So then using farm and gather epic you get extra xp while collecting trumpets back. Once at the end you’d enter portal to next planet and come back from there and be at the start of the farm. Plant, harvest and do portal again. Having enough trumpets could get you a level almost every 30 mins.
