This mod is a mod that adds an dimension as an extension of the deep dark accessible by ancient city portals, with this comes multiple infected mobs, blocks, items, even a new set of tools and armor above netherite!
Echo shards used to have only one use, being to make recovery compasses, but now there are multiple! Sculk used to only give exp, but now they drop items!
Many players found the deep dark and ancient cities kind of boring, with only a single entity accompanying them, and this mod is to give the players who wanted more things in the deep dark what they deserve.
I am currently working on an wiki for this mod, you can help by contributing here.
