This episode is currently nearly impossible to beat without, or even with boosters. Most of the levels in this episode are very hard, extremely hard, or even nearly impossible to complete. This is mostly caused by buffs, which makes the episode dependent on extremely insane luck to complete. This episode is currently one of the hardest, if not the hardest episode in the game. Please remove this template when certain levels are nerfed, which then lowers the episode's difficulty.
