Beat Expert Terraria but most of the map is submerged in water. Start with A Neptune's Shell, Starter Class Set-Ups, GlowSticks, (Mainly) Underwater Pets. This World Is Corruption because I Felt the Mana Regeneration Band was probably something Mages would find use full. If I get enough support I'll make a Crimson Version. To make it harder you can either not use the Neptune's Shell and/or Use Gills Potions. Everything Should be Accessible but may be harder due to the water breaking the plants on the ground. The Main Goal Should Be getting the "Super Absorbant Sponge" and drain the world. Anything you think would be a nice addition, feel free to comment and I may add it depending on how difficult it is. I've tried to find a map that was like this and fit what I wanted to do with it.
