Katters Structures - Deep Blue

Deep Blue is a sub-project of Katters Structures that holds only the Deep Blue content. It adds a brand-new dimension with Deep Blue Labs, Deep Blue Lab Ruins and Deep Blue City, and a set of curse and enchantment items such as Curse Alchemy, which grants random effects, and Ocean Heart, which grants Conduit Power Water. Ten or more new books with stories from the perspective of Nox are also included, and the Raj Lightning Rod and Enlightning Rod can be obtained through the dimension.

Enchantment Descriptions and Enchantment Lore show descriptions on enchanted books, which read like written books, and the mod works with compatible enchantments such as Enchantments Encore. Bosses in Deep Blue can be disabled, which also disables the structures and the dimension itself. Disabling only stops new spawns and leaves already spawned ones in place. Structures cannot be disabled through datapacks.

The mod is server required and client optional, so the server must run it while players may leave it out. It is published for Fabric, Forge, NeoForge and Quilt across 11 release versions, 1.21.5 – 26.3, and is released under a custom license that is not open source. Deep Blue is also available as a data pack. Running it on PaperMC or a fork such as Purpur requires allow-non-player-entities-on-scoreboards to be set to true in the Paper configuration.
