Cursed Skull

Cursed Skulls are a mob added in the 1.0.5 update that spawn in the Dungeon. They replace the Burning Skulls from versions 1.0.4 and below. These enemies float around with the ability to sink through walls and then pop back out; they suffer no weapon knockback effects, causing inexperienced or slow-attacking players to die more easily. They move in a sweeping motion once in range and never directly move towards the player once within range. These mobs can be very annoying if too many spawn. Their bodies flash through different colours as they move, possibly representing the magic they possess. A good tactic for fighting these would be to wait for them to begin swooping towards you then move or jump in the opposite direction of their movements, sidestepping them, or using wall-piercing items such as the Vilethorn or Dark Lance In this instance it is one of the only ways the Dark Lance can be used to penetrate walls. Note that once within range, the Cursed Skull will track the player's movements; using fast speed, wide-sweeping weapons will be useful when multiple Skulls are tracking you. Another helpful idea would be to use a Thorns Potion, but be wary when using as you will still take damage. As of 1.0.6, Cursed Skulls now have a chance to debuff the player with a curse on hit, preventing them from using any items for 3 seconds.
