This modpack is based off of PopularMMOs' modpacks and a few showcases. This let's return to the nostalgia you once experienced when you were a kid, since his websites went down.
Want bosses? There's over 70 of them, and you can choose from which one you want. Some bosses require more progression, some don't.
Want Adventure? You got it. There are around 10-20 different dimensions, each one being unique. There are also tons of naturally generating structures in the overworld to keep your desires filled.
Bored of that? Grow some diamonds or blaze rods with the Magical Crops mod, decorate your house in a unique way with MrCrayfish's Furniture mod, organize your items with the Storage Drawers mod, or learn magic from the Thaumcraft mod. The possibilities are endless, and the best thing is that you can go at your pace!
Night time is a very dark and terrible time to be out roaming the area. I'd argue that it's more difficult than RLCraft, with the combination of Advent of Ascension, Orespawn, Lycanites Mobs, and to top it all off with a cherry, Infernal Mobs.
Forgot to post updates to this! I will be adding some progression if you choose to progress rather than find out what to do.
Update 1: Released out of Beta! Renamed Modpack.jar.jar to Modpack.jar. I failed at common sense.
Update 2: Enabled Full King Power, or in more complexified terms, I enabled the Ultimate King in OreSpawn. In other words, be careful how many blocks of diamond you give your pet prince, because you may accidentally summon an unkillable, OP boss that will leave your current dimension in ruins. Just adds the ominous effect. If I were you, I'd kill my pet prince ASAP before I have the chance to feed it three blocks of diamond.
After a lot of work, typing, thinking, researching, and confusion:
Update 3: Added Simple Achievements and Starting Inventory, and with that, a Achievement book to make progressing less confusing.
