The Cursed Skull (and the Dragon Skull on Old-gen console and 3DS) is a flying enemy found only in the Dungeon. It is similar to the Meteor Head, with high damage, slow speed, and the ability to travel through tiles. It floats slowly towards the player, occasionally stopping to float in a circle around them for a while, before suddenly lunging forward to attack, similar to the Eye of Cthulhu. When striking a player, the Cursed Skull has a decent chance to apply the Curseddebuff. This renders the player unable to use items, including Weapons, Potions, and Grappling Hooks, making it very difficult to avoid further damage.
They are much more likely to appear in Dungeon areas where there are Brick Walls.
Cursed Skulls can be attacked through walls with melee weapons. Weapons with long range like Spears work well. This may, however, result in drops being trapped inside of the wall beyond the player's reach.
Cursed Skulls and Dragon Skulls can, rather rarely, drop more than 3/6Bones when defeated.
Cursed Skulls are effective enemies to farm for the Nazar, since they spawn more often than the few other enemies that also drop it. This should preferably be done in Pre-Hardmode, since it is more difficult to obtain in Hardmode.
