No real danger is present in this layer, as it serves as a transition from the mostly peaceful Sulphurous Sea. The Sulphuric Depths form the entrance to the Abyss and are mostly safe, consisting of 'islands' that generate in the middle and on the sides of the Abyss, with a few plants and decorations.The Abyss is divided into four distinct layers, each with a different set of tiles that generate and enemies that spawn.

Because many enemies in the Abyss are initially passive, only becoming hostile when hit or when in close proximity to the player, stealthiness should be greatly prioritized while exploring the biome. It is extremely deep, dark, and perilous, filled with deadly enemies, which increase in strength as the biome grows deeper. It is located under the Sulphurous Sea on the Dungeon side of the world through a chasm on the seafloor. The Abyss is an aquatic biome added by the Calamity Mod which spawns upon world creation. 'While there are many sightless crevasses in the deep sea, this one is a unique geological marvel.' If you were looking for something other than the Abyss biome, see Abyss (disambiguation). Wiki serves that purpose for us and frees up the devs to work on other stuff.The Abyss biome, as viewed on the map in a large world. I don't think it's a stretch to say the AI could form a rough map/database of info for the player to use. My justification for using wiki is that the AI is so advanced in-game it could probably create an extensive database/map out of all the scanning the player does.

It's your choice how you want to approach the problem. This kind of self-discovery exploration is part of the game's charm though. Locating specific stuff in this game can feel like searching for a needle in a haystack if you aren't familiar with the map. I spent hours trying to find the entrance to Lost River until I finally gave up and used the wiki map. I would've been crazy frustrated trying to sort out the intended order the clues are meant to be given and figure out where to go next. It was really confusing discovering some story locations out of order and getting conflicting directions from all the PDA entries I was discovering.

I feel like the wiki is mandatory at some points if you don't follow the story in the exact intended order, this is not a game you can casually play and have everything handed to you.
