Find different ways to defeat the queen and the king. Explore the space if you get bored of the overworld. Battle boss in space if you want. Also build a park with all the mob in the pack maybe not the boss. These are my favorite mods so far. PS. the first Soulis is still up it is broken at the monument will not be fix as this one is the newer one also yes the other Soulis modpack is mine just on a different account.
