⬇ Download on CurseForgeThe author built this one for Minecraft 1.21 on Forge. On other versions it may install and then do nothing.
5 Dimensions full of blocks. Each dimension is made entirely out of a block that is used to make tools. When you craft the blocks together, you get a bonus dimension with every block from the other dimensions. If you place a Magic Throne, crafted by 4 magic blocks and a carved pumpkin, the Magic King will appear!
When a block that is used to make tools is crated with a lava bucket and a raw version of that block, you get a portal igniter. If you use a portal igniter with a nether-shaped portal that corresponds with the igniter, you will create a portal to that block's dimension.
If you place a campfire by a villager, it will turn into an explorer, which trades Magic Gems for rare items. If you craft a torch with a staff instead of a stick, it will make a magic torch. When that magic torch is used on a villager, the villager will turn into a Spy. The Spy is one of the 4 new bosses(including the Magic King).
If you find a place made of magic material, go inside of it an attack the sword holder. When the sword holder is attacked the Mage(another boss) appears!
If you stonecut a bone block, you will get a skeleton block. When placed, the skeleton block summons another boss called The Magic Skeleton.
