YUNG’s Better portals Mod (1.16.5), enhances vanilla portals to make it more immersive and engaging. This mod is designed to reinvent the vanilla Nether Portal system. Instead of making a boring obsidian rectangle and setting it on fire, nether portals are now available in the form of Dimensional Rifts. These can be found deep underground. To reach the Nether, you’ll need to locate one of these Rifts – but it’s only a one-way journey.
You will need to find a Monolith in order to return from the Nether. These semi-rare, new structures can be seen from far away by the beams that they emit into the sky. A Reclaimer is the block that shoots this beam from each Monolith. It’s the key to the Overworld. The Reclaimer can’t work without power. To power the Reclaimer, you will need to place a gold block onto each of its four sides. This should not be difficult in the Nether. Once you are powered up, the Reclaimer can lift you into the Overworld.
