Not to be confused with Skeleton, an enemy found underground, or Skeletron Prime, the Hardmode version of Skeletron.

Skeletron is a pre-Hardmode boss. It must be defeated before travelling through the Dungeon. It is immune to the Poisoned, On Fire!, and Cursed Inferno debuffs.

Defeating Skeletron grants unlimited access to all Dungeon areas for all players. It also causes the Clothier NPC to spawn, as long as a vacant House is available.

If you enter the Dungeon before killing Skeletron, Dungeon Guardians spawn once you reach 0 depth, generally killing any player with a single hit. Additionally, if the Dungeon Guardian is killed, access is still not allowed to the Dungeon until Skeletron has been defeated. The Music is Boss 1.

Summoning[edit | edit source]

Skeletron is summoned by speaking to the Old Man at the Dungeon's entrance, at night, who will die and spawn Skeletron when you select the “Curse” option. If you speak to the Old Man during the day, he will ask you to return at night. You will only be able to summon Skeletron once per night, as the Old Man will not respawn until day.

Skeletron can be summoned repeatedly this way until it is defeated. Once it is defeated, the Old Man's curse will be lifted and he will no longer appear. The Clothier NPC will arrive, bearing a remarkable resemblance to the Old Man. He can move in a town, as long as there is an empty house for him to live in. Skeletron can be re-summoned thereafter once the player acquires the Clothier Voodoo Doll. Equipping the accessory allows the player to kill the Clothier, which summons Skeletron. However, this will only work at night, and doing so at day will kill the Clothier, but not spawn Skeletron.

Attack Phases[edit | edit source]

Skeletron is a large floating skeleton head with two independent floating hands. All parts can travel through blocks, and will attempt to make contact with the player to inflict damage. Each part can be killed independently, but killing the head is all that's required to defeat Skeletron.

Skeletron alternates between two attack phases:

  1. The head remains above while the hands slash at the player.
  2. The head spins, dealing significant damage if touched, but dropping its defense to zero for the duration of the attack.

If the player takes too long to kill him and dawn arrives, Skeletron will begin acting exactly as a Dungeon Guardian, performing a head spin attack with very high damage, which will usually kill any players remaining in the vicinity quickly (it is still possible to kill him, but players are at an extreme disadvantage). Skeletron remains in this form until dying or despawning, even if players manage to avoid dying until the following dusk.

Expert mode[edit | edit source]

Skeletron has additional properties in Expert mode:

  • Skeletron's Head is near invincible, but after losing both of his hands his head becomes vulnerable. Once either of its arms are destroyed, the head will begin to shoot homing skulls resembling Cursed Skulls at the player, increasing in frequency as his health gets closer to 0.
  • Skeletron moves faster and has better A.I. when targeting multiple players. With this, he is able to "stunlock" you while spinning, able to almost instantly kill players if they aren't able to escape. (e.g., by using a Grappling Hook.
  • Skeletron is also able to inflict a couple of debuffs: the hands inflict Slow, while the head inflicts Bleeding.

Notes[edit | edit source]

Old Man at the dungeon
  • The Old Man who stands in front of the Dungeon can be killed if his health is depleted. However, this does not count as a Skeletron kill, and he will respawn. Entering the Dungeon and descending below 0 depth will still allow Dungeon Guardians to spawn.
  • Skeletron disappears when all nearby players are dead, and the Old Man will respawn the following day.
  • If Skeletron has not been killed by dawn, it will get increased defense and damage, making it very much like the Dungeon Guardian.
  • If Skeletron is killed in its daytime form, it will still drop the normal Skeletron loot, open the dungeon, and grant the Boned achievement.Pc only.png
  • In Expert Mode, if any of Skeletron's hands are taken out, he will start shooting homing skulls at the player.

Tips[edit | edit source]

For more elaborate strategies on defeating Skeletron, including Weapon and Arena recommendations, see Guide:Skeletron strategies.

  • If a Magic Mirror or Recall Potion is used, Skeletron won't follow the player back to spawn, and will despawn instead.
  • Don't jump onto Skeletron's head multiple times with the Slime Mount, as going too high will cause him to despawn (also, in Space the slowed falling will make it almost impossible to get back down past him). However, inside of the Dungeon entrance the Slime Mount can be a valuable tool.
  • Going fast enough on a Minecart can cause the hands to despawn, leaving only the head to fight.
  • Using any ricochet weapon (such as the Water Bolt found in the Dungeon) is extremely useful.
  • With multiple players, it's a good idea to set the spawn point (a bed) near the Dungeon, so that players can simply rejoin the fight if they die.
  • Using the Bee Gun or The Bee's Knees with the Necro Armor, which both fire homing bees, can quickly build a swarm of constant damage.
  • Attacking the hands first is advised, as destroying them both will make it very easy to dodge Skeletron for the rest of the battle.
  • In Expert mode, Skeletron has over 100 defense until the hands are defeated.
  • In Expert mode, if the player keeps moving in different directions, most homing skulls will miss, also note that they do not travel through tiles.
  • In Expert mode, it's also a good idea to use a Yo-Yo and an overhead barrier, however quick movement is needed to avoid it when it starts to spin.
  • In Expert mode, going too far from the Dungeon will cause Skeletron to kill the player with a single hit.

Trivia[edit | edit source]

  • Assuming that the player is at 5 ft. 9 1/2 in. (1.75 meters) In terms of height, Skeletron's Head would be about 11 feet (3.35 meters) tall and 8 feet (2.43 meters) wide. The Hands would be 10 feet (3 meters) tall and 7 feet (2 meters) across.
  • At one point, Skeletron heads protected the Dungeon, but when one was killed, it would count as killing Skeletron, so the Dungeon Guardians were introduced to protect the Dungeon instead.
  • With his hands combined, Skeletron has even more health than the Expert mode Wall of Flesh.
  • Skeletron is the only boss not to have any guaranteed drops (with the exception of the Lesser Healing Potions and Treasure Bag if in Expert mode).
  • Dungeon Guardians have the same head as Skeletron.
  • On the Desktop version of Terraria, the Old Man has a health bar, but on the Mobile and Console versions, he is completely indestructible to the point where he does not have a health bar.
  • In the Terraria and Edge of Space crossover teaser, Skeletron turns into an actual boss called Omegatron.
