Hermit Crab

The Hermit Crab is a ground-based monster in Risk of Rain 2 that looks and serves as a mortar.

The challenge The Demons And The Crabs 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 that they are not easily taken care of when spawned in.

A Hermit Crab will frantically scuttle away from any danger within 3 player spaces, and after 5 player spaces will bury itself back into the ground to continue firing.

If there's no target in sight, a Hermit Crab will instead actively hunt down a target. It will resume its regular behavior once a target is in sight.

Bury + Mortar Volley
A Hermit Crab's only skill is to bury itself into the ground. While in this buried state, the Hermit Crab launches a boulder at the targeted area, dealing 1200% 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 shot.

Tips

 * Try to make a point of taking out Hermit Crabs whenever noticed, either directly or indicated by the mortar. A single one on its own is not particularly dangerous, but they can quickly become a problem if too many are left untouched.
