Skeletron

Skeletron is a pre-hardmode boss that consists of a head and two arms. For new players this boss can be difficult and it is recommended that the player fights it after they have defeated the two other pre-hardmode bosses The Eye Of Cthulu and The Eater Of Worlds as these bosses provide the player with good armor and weapons needed to fight Skeletron. Skeletron is summoned by talking to the Old Man at the dungeon at night time when he gives the option to take on his curse, the Old Man will die and Skeletron will be summoned. Skeletron drops lesser healing potions the book of skulls, Skeletron hand, Skeletron trophy, or the Skeletron mask. Once Skeletron is defeated the player has access to the Dungeon.
