prismarine items
by Ehm1k
Prismarine Items, a NeoForge adventure mod for 1.21.1, adds an underwater ore biome with its own blocks, items and a pickaxe.
What it does
Players who explore the seabed find a new biome where prismarite grass grows and ore deposits appear. Breaking those deposits drops prismarite fragments, which the mod uses for its crafted items. The added pickaxe can break every ore down to diamond, so it covers the full range of common ores.
Prismarine Items needs NeoForge and runs on client and server, so the server and every player need it. The latest NeoForge file is 1.1 for 1.21.1, published on 2026-07-17, and the code is not open source; it is released under All rights reserved.
