They attack approximately once every 4 seconds and the animation can be interrupted by attacking the shooter. When the arrow is being charged, energy can be seen accumulating at the tip of the crossbow. The arrow can be dodged by dashing, but only at the last moment, since the target is locked only just before the arrow leaves the crossbow.
Some Hilichurl Shooters, mostly those in the Spiral Abyss, Domains, or overworld events/challenges, are capable of firing five bolts at a time, generally covering a 90 degree area in the direction they fire from.
While weak individually, Cryo Shooters are often see with other elemental enemies, which can cause dangerous Elemental Reactions.
