Peace Mode

The Peace Mode is a counterpart to The Epilogue and the Dream Mode, but to activate this mode, you have to beat the Ancient Cultist. The spawn rates are also lowered down, but even more. Like, a regular slime can spawn only at 10% in Purity. You also obtain the Green Flag to team up with purity, but the flag is even usable in War Mode. Now, about the facts.
