Sea Prisms are a Pre-Hardmode ore found naturally generated within the Sunken Sea and can be crafted using Prism Shards. They require at least a Gold or Platinum Pickaxe to mine. They are used as crafting materials in several weapons themed around the Sunken Sea, as well as Mollusk armor and pieces of the Eutrophic furniture set. They are also used to craft Tesla Potions.
