This is my main mod. It works well with the More Stuff mod, but that is in no means required to enjoy this mod.
This mod adds a ton of new advancements, blocks, and items, on top of 2 new mobs, a ton of new potion effects and mechanics, a new biome, 3 new dimensions, and a ton of new music discs!
This mod shouldn't require any other mods to run and is unlikely to cause major strain on any sufficiently powerful hardware.
You should download this mod if you like random fun and silly features that don't do much (for the most part) and if you like having more dimensions to explore, blocks to build with, and/or music discs to listen to!
In terms of blocks, this mod adds quite a lot, including a new wood type, two new sets of stairs, slabs, and walls, and various other random blocks that could be used for building but are mostly just memes.
For items, this mod adds two new weapons, the Pitchfork, which just looks cool and does not have any special gameplay features, and the Darksand Blade, which inflicts blindness onto whoever it hits. This mod also adds some other items, however they're all either portal ignitors or crafting ingredients and are thus barely worth mentioning here.
As for mobs, this mod only adds two creative mode exclusive mobs, the Radiance Slime and the Darksand Zombie, which are both bugged and hardly worth mentioning as I'm still learning how to properly add mobs.
Next, for biomes, this mod adds the extremely rare Weeping Woods, which is comprised of weeping trees which give the new weeping wood type, which sports a unique indigo colour.
This mod adds a lot of potion effects, such as Drowsiness, Adrenaline Rush, and Adrenaline Exhaustion.
Advancements are one of the features that this mod adds the most of, with over 40 unique ones to achieve!
For fluids, this mod adds the incredibly viscous Crude Oil, which pulls you towards its center like quicksand once you enter it but doesn't deal damage nor destroy items, and its polar opposite, Engine Oil, which DOES deal damage and destroy items and is the new least viscous fluid in the game.
Finally, this mod adds three new dimensions, the Radiance Layer, the Dark Place, and the Liminal Abyss, each with their own music, generation, and surface blocks.
