This enemy attacks by dropping a yellow bullet. This attack is simple to dodge but it has a moderate damage output. This enemy always appears in large swarms, which can result in heavy damage. It is highly recommended to keep melee characters out of the fight. Freezing them with the Freeze Explosion orb will disable them, making them rather trivial. If freeze weapons aren't available, then ice weapons will do the trick. Be wary of the White Roundhead Walkers when doing this as they have infinite range. Also, the Grey Roundhead Trees can give protection to them if they fly low so watch out for that.
