Dark utilities is a mod that adds a fair amount of varied content to the game, focused on covering various features. You could say that it adds random content to the game, i.e. blocks and objects that claim to add new functions to cover various aspects of the game, instead of focusing on specific, defined features.
By installing this mod we can find conveyor belts of objects, blocks and entities, as well as blocks and objects whose appearance we can change to hide them and hide them from other players, thinking that they are something else. We can also create different types of traps, a more efficient hopper and rings that improve the abilities of enchanted objects, among other things.
