Large enough to warrant its own post, I was responsible for creating a "Drowned" variant of my Coastal Caves tileset. Overgrown with barnacles, slime, and the corruption of the Drowned, I made a version of the Caves with a much darker, more oppressive atmosphere. In addition I got to create the Large Arena for the Lobstrocity boss fight, where I had to combine the natural structures of the Coastal Cave and the Corruption of the Drowned with the Architectural stylings of the Firstborn (another tileset added in Lord of Hatred). The Firstborn ruins gave me a chance to really layer my storytelling as a sacred site that has gone through multiple different owners.
The Drowned makeover would not have been possible without Nora Nirvaluce, who did the amazing work lighting the tileset.
