According to the description of the Harvest craft: "Change a Unique Bestiary item or item with an Aspect into Lures of the same beast family", the player can also use non-unique item that has the Aspect of the Crab item mod (of Craiceannof Craiceann Suffix Grants Level 20 Aspect of the Crab Skill) as an ingredient. [1] The latter can be self-crafted using beastcrafting, or drop from specific Azurite Mine node.
