Like their cousins, all of this enemy type appearing on the screen attack in unison. They will also attack in tandem with their pink cousins and Yellow Mask Trees (though differently due to the higher AGI of the latter). However, this enemy fires many more projectiles, but each projectile deals lower damage. Freeze type weapons are the best options against the large groups these enemies appear in, especially the Magician's Freeze Explosion 6. They are also great for gold and EXP harvesting, due to the the large swarms they appear in.
Along with its pink cousin, this is the first enemy with more than the necessary amount of range to fire from one side of the screen to another, with 1000.
