Worser than barley (WTB) is a mod heavily inspired by wheaten eye's "wheat death of the universe" mod(which you should check out btw that mod is PEAK!) that makes the player spawn in a new dimension upon joining/creating a new world(and makes the player respawn in it) so it isn't really recommended to add this mod to an existing modpack.
slightly changed progression
there are currently
-8 new biomes
-4 new dimensions(with more planned for later progression)
-5 bosses
-alot of new ores
-alot of new blocks and items
