Gem Crab

Gem Crab is a crustacean creature distinguished by crystalline outgrowths on its shell that closely resemble ancient gemstones. Localization entries describe its scarcity differently: some sources label it "uncommon," while others call it "rare." The species appears in the Encroachment environment and is primarily notable for its distinctive crystalline Carapace and its utility in crafting.

The crystal formations sprout from the Carapace and give the Gem Crab both its value and its recognition in recipes and collection lists. It is used as a crafting ingredient in various item recipes; details of those recipes are provided elsewhere in the crafting documentation.

Acquisition is narrow and specific. The Gem Crab can be obtained through a trade interaction in the Encroachment: trade Powdered Crystal to the Hive Larva while you are wearing the Hive Larva Suit. This trading method is the documented route to secure Gem Crab specimens for use or crafting; there are no other confirmed natural spawn or guaranteed drop mechanics listed in the localization sources.

Practical notes and interactions:

• Appearance and identification: look for crabs with gem-like crystalline protrusions on their Carapace; these visual cues distinguish Gem Crab from ordinary crab variants.
• Acquisition method: obtain Powdered Crystal, equip the Hive Larva Suit, find the Hive Larva in the Encroachment, and complete the trade to receive Gem Crab.
• Crafting role: Gem Crab is consumed as an ingredient in crafting recipes; check recipe lists to see which items require it.
• Fishing interaction: localization indicates the Gem Crab can be applied to fishing equipment to alter fishing results. The entries state it can be added to a fishing rod to influence catches, though exact catch modifiers or enabled catches are specified in the equipment modifiers documentation rather than the localization descriptions.
• Rarity and value: because localization terms vary between "uncommon" and "rare," treat Gem Crab as a moderately scarce resource; prioritize acquisition when a current crafting need exists.

This concise summary reflects the available localization and in-game usage information: a visually distinctive, craftable resource obtained via trading with the Hive Larva in the Encroachment while wearing the Hive Larva Suit, and usable both in recipes and to modify fishing behavior.
