The extra utilities mod for minecraft adds a variety of new and interesting blocks and items to craft within the basic game of Minecraft. Among these new assets, this mod allows you to color your blocks, experiment with lighting, arrange a death trap for dungeon projects, and even establish your own automated mining rig.
These are special blocks in that they do not require a solid surface to work on; you can place them in mid-air. An Angel Block can be quite useful when you want to work on a skyward project without some form of scaffolding. They also break instantly and automatically enter your inventory when you do break them.
Given the sheer variety of playthings that this mod bestows, there’s little reason for a player not to install it.
