The Demons And The Crabs Challenge requires the player to chase 20 Hermit Crabs off the edge of the map for it to be completed.

Environments

 * Titanic Plains (only after Looping)
 * Abyssal Depths

Skill & Behavior
Hermit Crabs initially spawn a distance away from the player(s), so to not be harmless and easily taken care of when spawned in.

Hermit Crabs will run away from any danger within 3 player spaces, and after 5 player spaces, will proceed to bury itself back into the ground so to resume firing.

On the contrary, if there's no targets in sight, Hermit Crabs will instead actively hunt down a target. Likewise, it will resume its regular behavior once a target is in sight.

Bury + Mortar Volley
Hermit Crabs only skill is to bury itself into the ground. While in this buried state, the Hermit Crab will proceed to passively launch 3 boulders at the targeted area, each dealing 400% damage with a Proc Coefficient of 0.5.

The Bury has a cooldown of 3 seconds, while there's a 5 second cooldown between the firing of the Mortar Volley.
