Prismite Trident

The main ingredient in this mod, prismite, is crafted with one diamond, one gold ingot, one prismarine shard, and two prismarine crystals. With prismite, you can either craft guardian armor that offers infinite water breathing when the whole set is worn, or you can craft prismarine rods (3 prismite + 4 prismarine shards = 2 rods) to craft a trident.

Crafting the Trident

Elder guardians now drop one sea shard each (clearing an ocean monument will net you three sea shards). By combining two prismarine rods and three sea shards, you can craft a trident. Additionally, a trident can be repaired by holding a prismite ingot in your offhand and right clicking. This restores one quarter of the triden't durability at no XP cost.

Elder Guardian Helmet

You can upgrade your guardian armor by combining the guardian helmet with a heart of the sea in a smithing table to receive an elder guardian helmet. While wearing this helmet and the rest of the guardian set, you are granted infinite conduit power. Alternatively, the elder guardian helmet can be worn with any other combination of armor and still grant infinite water breathing.
