Phantom Skeletons are very dangerous mobs that possess various abilities. They only spawn in Phantania, usually alone. They have 60 <3 and can be potentially life-threatning without the right tools to fight it with.
Phantom Skeletons can shoot four arrows at once, each firing dead straight and much faster than a regular arrow. Because of this, they are the mobs with the highest chance of killing the Player. They can be a nuisance, but they only spawn by themselves instead of in groups. They circle around the Player giving them random curses that hinder their speed or they slowly take damage. The arrows can be deflected with a sword that is Ruby or better, and the Phantom Skeleton may take the curse instead. They have a high chance of having attacks go through them, though, and they are hard to fight. When killed, their rare drop is a Phantom Bow.
Phantom Skeletons spawn alone in Phantania, but they can also have a chance of spawning when a Phantom Zombie dies (40%), however they have half the health as usuall.
