the hardest level in all of the game not just in traditional terms but also in speedrunning, so many RNGs not only does it delay time but also could kill the run. 1st the sappers sensitive to damage and might explode not when their HP reaches 0 but close to it plus protecting 4 of them. the other RNG part comes with Priestesses 4 you must fight in mini boss battles, where they land is RNG for close combat. last RNG is with the final boss Sejanus where he spawns and what attack he does, add that with the zombie horde attacking you.
