Description
Sea Lantern generates exclusively in ocean monuments — the massive turquoise pyramids guarded by guardians and elder guardians at the bottom of deep oceans. Each monument contains roughly fifty of them embedded in the prismarine walls and floors. The block can also be crafted from four prismarine shards and five prismarine crystals, both also looted from monuments.
The defining feature is light without compromise. The block emits level fifteen brightness — the maximum in the game — and works perfectly underwater, where torches go dark and lanterns hang awkwardly. Sea Lantern is the standard ceiling and floor element of underwater bases, conduit chambers, and aquarium builds. Mining without Silk Touch destroys the block and drops two to three prismarine crystals (Fortune adds bonus rolls). Mining with Silk Touch returns the block intact, the only practical way to relocate them once a monument is cleared.
