What it does

The mod adds content built around the word Jub, a choice the author explains as a funny word. The additions include a new dimension called Juber Dimension, reached through a portal made of cobblestone and ignited with dirt and a plant named Jubant. Ruined portals can generate in the world and lead to the same dimension, though they hold no loot. The dimension has a custom biome, its own structures, a new block and a new liquid.

The author notes that stone pickaxes can break some of the new blocks. Only wood-based structures appear in the dimension, so players who want more wood need to gather it there before leaving. The mod also adds two new mobs, one of which is a boss that spawns often, along with new tools, armor, an armor recipe, a painting and an enchantment. The author notes that the originally planned name was changed because MCreator could not rename the mod later. The mod is client and server, so both the server and every player need it. It is published for NeoForge 1.21.8 under All rights reserved, and it is not open source.
