Update Version 1.2.4:

Two achievements have been added, ‘Cursed Armour’ (given when you have all the cursed armour and you get the item ‘Cursed Flint’) and ‘Cursed Tools’ (given when you have all the cursed tools and you get the item ‘Cursed Steel’), also the ‘Cursed flint and steel’ and its crafting has been added. Also the ‘Deep void’ dimension has been added, you enter it by using the new mech in the big portal of the ancient city, in it spawnean endermans and oscubes (a new mob that when you attack it runs away and then attacks you and has a 10% chance to give you a mimic crystal, which makes you invisible for 10 seconds). The blocks in this dimension are the sculk block and the ‘Deepsculk’, a new block that you break with the hoe and gives you experience, it also adds a new ore called Obscurite, which has its Ore, its raw ore (which turns into an ingot in a smelting furnace), its ingot and its nugget, plus the Obscurite armour, which when you put on the helmet removes the blindness of that dimension and gives you night vision (because entering the dimension gives you blindness), and there are also portal structures, so you can exit the dimension.
