This mod adds a new tools and armour set which is quite a bit better than diamond and it can be crafted with a material that you can get by mining glitched blocks which can be found fairly deep in caves. The glitched pixels are used to craft items like the glitched rod and apple, and the glitched rod is used instead of a stick for crafting the tools. The glitched apple will grant you 14 hunger points when eaten, and absorption for a small amount of time. The glitched potion gives you invisibility, speed, haste, and jump boost for 1 minute. The glitched scythe is the best weapon in the mod and it deals 12 damage.
Also, if you have already downloaded this mod, but only have the first version, then you need to replace it with a version that has a v and a number after 1.12.2 in the file name.
If you play with the version of this mod which doesn't have v and a number after 1.12.2, then it will be impossible for you to mine glitched blocks in survival. This also means that you won't be able to collect any of the other items from the mod, as they require you to use glitched items to craft them.
Version 3 changes:
Added unstable glitches (Used to craft the glitched scythe blade.)
Added the glitched scythe blade (Used to craft the glitched scythe.)
Added the glitched scythe (The best weapon in the mod, it swings as fast as a sword and deals 12 damage.)
If you only have the previous version of this mod then you need to replace it with the newest version, as the first version has a bug which stops you from being able to mine glitched blocks in survival mode. This means that none of the other items from this mod are obtainable in survival either unless you use version 2 or higher.
