Dimensional World Mod brings to the Minecraft world a brand-new Dimension in which you can do whatever you want even the dimension particularly for Minning . For instance, you can try creating a special type of Bricks by crafting some Stone Bricks with a Pickaxe.
These special bricks are not only harder to break but also are the door for you to join a new world: the Mining world. You might want to make an attempt to build a wall with five blocks high and four blocks wide with a three by two hole in the middle like the shape of a Nether Portal.
After actually creat the Portal by using a new Tool, try to get the Portal Igniter (also called Portal Multitool) from crafting a few Stone Bricks, a Flint and Steel and a Stick. Now you just need to right-click the Portal Frames and watch! You won’t be disapointed !
