Crafting Sea Lanterns: The Basic Recipe
To make a sea lantern in Minecraft, you’ll need 4 prismarine shards and 5 prismarine crystals arranged in a specific pattern on your crafting table. Place the prismarine crystals in a plus sign formation (center and four cardinal directions), then fill the remaining four corner slots with prismarine shards.
Gathering the Required Materials
Both prismarine shards and crystals drop from guardians and elder guardians found in ocean monuments. Guardians drop 0-2 prismarine shards and have a 40% chance to drop prismarine crystals. Elder guardians are guaranteed to drop prismarine crystals but are much rarer.
You can also find these materials by mining prismarine blocks in ocean monuments, though this requires a pickaxe and underwater breathing preparation.
Alternative Methods and Considerations
While some players have suggested using glow ink sacs as an alternative crafting ingredient, this isn’t currently possible in vanilla Minecraft. The traditional guardian farming method remains the most reliable approach.
For large-scale projects, consider building an automatic guardian farm near an ocean monument. These farms can provide steady supplies of both prismarine materials and the raw fish that guardians also drop.
Tips for Efficient Sea Lantern Production
Since each sea lantern requires 9 total items, plan your guardian hunting accordingly. Bringing a Looting III sword significantly increases your chances of getting more drops per guardian killed. Water breathing potions and night vision potions make underwater combat much more manageable.
Sea lanterns provide the same light level as glowstone (15) but offer a unique underwater aesthetic that makes them perfect for ocean bases and underwater builds.
TL;DR
Craft sea lanterns using 4 prismarine shards and 5 prismarine crystals in a plus pattern. Get materials by defeating guardians in ocean monuments.
