The Spined Shellbeast is an elite enemy in the Reclamation Algorithm game mode of Arknights.

Enemy description

A type of hard and prickly shellbeast. If it retracts its head into its shell, just save your energy.

Overview

A Terran animal resembling a cross between ceratopsids and armadillos, the Spined Shellbeast is a rare Wild Beast that could appear as a special Raid made up solely of the Shellbeast itself; thus it is able to move between zones every day, making it highly elusive. The Shellbeast can be made to spawn in the following day by expending 15 Rice on Encounter: Side Effect.

The Spined Shellbeast yields 2 Cartilage Chunk that are required for making high-quality Provisions, and while the Shellbeast does boast significant HP, the other stats are average at best and it won't even try to run away from the would-be hunters, unlike the Sandfall Crystalhoof, but its ability can make it problematic to deal with.

Ability	Init. cooldown	Cooldown
When taking damage and not being Stunned or Frozen, the Spined Shellbeast retreats to its shell after 1 second,* during which it gains the following traits: Neither does move nor attack. Takes no Physical and Arts damage. Immune to Stun and Freeze, and cannot be shifted. When attacked, the attacker takes Physical damage equal to the Spined Shellbeast's ATK. Emerges from the shell over 1 second if not attacked in 10 seconds.	Passive

As such, it is recommended to either use sources of burst damage capable of shaving off large chunks of the Spined Shellbeast's HP in one strike or bypass the shell with True damage (Elemental Damage is not an option since they are based on the damage dealt, with an exception to Virtuosa's Wordless Elegy).

The Spined Shellbeast cannot be captured by regular Beast Traps, but can be captured with the new Hunting Net Launcher from Tales Within the Sand's Expansion II.

Before Expansion II, it notably cannot be captured even though an image for their captured version (see the infobox) already existed in the game files at the time.
