Strategy[ | ]

  • Your web-sling ability lets you easily traverse through the arctic and the arctic deeeep, which depending on the map you're in, can have lots of terrain, or next to none.
  • Your ability to inflict bleeding is unique; Colossal squids aren't as fast as Japanese spider crabs.
  • Your main prey should be non-tank opponents that are susceptible to bleed damage.
  • Do not overuse your web-sling ability for offense, rather use it to grapple to large patches of food or algae, to recover your health.
  • You are not buoyant, but you can use this to your advantage when your prey is moving down; your non-buoyancy will move you faster than the animal.

Skins[ | ]

The Japanese spider crab currently doesn't have any skins.

Trivia[ | ]

  • The Japanese spider crab's ability is a play on the word spider, and how spiders can use their webs for travelling.
