Guide:Skeletron strategies

Skeletron is a boss guarding the Dungeon, and killing it is necessary if you want to access the loot within. He's big, tough, hard to dodge, and can seriously ruin your evening many times over. Like any other daunting task in Terraria, defeating him is largely about smart preparation. The following are some hints, tips, and strategies to help you defeat it.

NOTE: This guide was designed for version 1.0.5, balance changes have been made since then and some information might not be valid.

Weapon selection
When choosing one strategy over another, the biggest factor in your decision is likely to be weapon constraints. For Skeletron, ranged attacks are far more effective than melee attacks with very few exceptions. The first time a player fights Skelly they are unlikely to have many high-end pieces of melee equipment so ranged attacks are more often used.

Ranged weapons
Skeletron's high defenses mean that most of the mid- to low-tier weapons aren't worth the time or money, so shurikens are pretty much out. Spiky Balls work great when spread around the Dungeon entrance, but they will disintegrate and can't be recovered once thrown.

The best way to go is combine high to moderate damage with a fast rate of fire: The Flamarang and Thorn Chakram are both reasonably easy to get by this point, and either the Demon Bow or Molten Fury will do the job admirably. Most pre-dungeon guns don't have enough damage-over-time to be useful, with the exceptions noted below. The Minishark is great, as is the Star Cannon, but both of these are expensive to use: the Star Cannon requires about 100 stars to do the job and the Minishark needs about 700 to 1,000 rounds of standard musket balls if you aim carefully (1250-1500 musket balls for the players with bad aim).

A bow and some decent arrows are comparatively much easier to get your hands on. A high-damage bow will be doing most of the work for you in such a case, so the difference between weak-but-cheap ammo and rare-high-damage ammo is a matter of personal preference.

Melee weapons
The non-ranged and semi-ranged weapons have some use, but generally don't stack up to the ranged family. Flails are excellent for damage and can consistently dish it out, but the Sunfury is impossible to obtain without a Shadow Key (found in the Dungeon) and the Ball 'O Hurt is at the low end of the damage scale. The Fiery Greatsword does high-end damage and has excellent range for a melee weapon but is so slow to swing that most other weapons will outstrip it in the long run.

Other
One slightly different approach is to use a tool with auto-swing, i.e. The Breaker or the War Axe of the Night, both of which are relatively easy to get materials for with lower-end gear. Neither has as much damage over time compared to the options above, but these weapons will keep swinging as the mouse button is held down, allowing you to concentrate on dodging.

Using a Space Gun frees you from the constraints of ammo and deals decent damage, but you will need a lot of mana potions or Meteor armor to last the fight.

Dungeon weapons
Also to consider are these weapons not mentioned above: All of these weapons are as good or better than the other weapons in their respective categories but are found only in the dungeon, and thus cannot be obtained without either defeating Skeletron or trading with other players. A side option is to go in the dungeon at night, which spawns Skeletron as his regular self, not his Dungeon Guardian self, and to outrun him long enough to gather keys and open enough chests to find the good dungeon items.
 * Muramasa: Much like the War Axe and The Breaker, this sword has auto-swing and good damage output, not to mention a decent swing radius and speed. Just hold the button down and you're good to go.
 * Handgun and Phoenix Blaster: Easy to get ammo for and the Phoenix especially has stellar dps.
 * Blue Moon: An upgraded Ball 'O Hurt. Used the same way, and once Skeletron is down it's arguably easier to get than Sunfury.
 * Aqua Scepter: This weapon is best used with the Blue Moon or a ranged weapon, don't count on it to single handedly take down Skelly. Blast away with the scepter then switch to something else while your mana recharges or just use potions.

Arena


The arena doesn't matter as much as it does in the other boss fights, but it can still be important. A large, flat surface with enough room to maneuver is key. Wood platforms may be used with decent effect, but keep in mind that they take time to drop through when dodging and too many platforms can interfere with attacks depending on the weapon/ammo used. A fairly straightforward and common practice is to simply flatten out the roof of the dungeon and fight Skelly there. Keep in mind that the fight must occur at night, so you'll have to be comfortable dealing with Zombies and Demon Eyes (and possibly Eaters if you're near any corruption) or build a platform inaccessible to them. A ceiling is mostly unnecessary and tends to get in the way of many attacks.

Boomerang/Chakram users may prefer to fight Skeletron in the dungeon entryway to provide a ceiling for missed shots to return faster. Bow users can benefit from having a lot of open space to collect fallen arrows as they go. Melee users will want more platforms to aid mobility.

Armor
The more armor you have, the better. You should use the best armor available to you at the time, but if the best you have is Silver armor or lower then you should seriously consider holding off and continuing the fight later with better defenses. Shadow armor or better is highly preferred. And, as always, having more HP is a good thing. If your armor is far ahead of your weapons then you can sacrifice killing power in favor of survivability.

Ironskin Potions will make the job easier for any player and are highly recommended. Two potions will last from sundown to dawn, provided the player stays alive the entire time.

Avoiding attacks


Skeletron attacks by either hitting you with his hands or spinning his head at you. Both attacks seem to come equally frequently unless one or both of the hands has already been killed.

The hands are difficult to dodge and will mostly come in from the sides. Both hands or one hand will attack at random, but just before this they will draw away from you in a kind of "wind-up" motion, then strike toward you and continue for a good distance onward. If you learn to read this attack it can be avoided more easily. Keep in mind that only the hands that will damage you; Skelly's arms take up a lot of space and can be distracting, but they won't block your bullets or hurt you. Avoiding the attack is simply a matter of jumping at the right time: jumping too late won't give you enough time to dodge the hands and jumping too soon will let the hands adjust to your new position and hit you anyway. Wait and dodge the hands only after they've started their strike.

The head attack is much slower, but Skeletron's massive noggin does more damage and takes up a lot of space, especially when it's spinning. This makes the head somewhat difficult to dodge without the aid of Rocket Boots or another jumping aid, or platforms. (The upside is that this is a great time for boomerang users to rack up a ton of easy hits in a hurry, by staying just in front of the head and attacking like mad.)

General tips

 * The hands are probably your biggest problems and have lower HP than the head, but it is not necessary to destroy them, since if the head dies the hands die with it. If your weapon does low damage at a fast rate then it's best to ignore the hands and concentrate your fire on the head.
 * It's always preferable to summon Skeletron immediately after sundown since the fight must be finished in one night.
 * The lower your damage per second, the longer the fight will last. This also means that you're likely to need more potions and ammo.
 * If you are using a weapon with ammo, always have a backup sword or boomerang handy. The Zombies and Demon Eyes that you will encounter during the fight may not be worth wasting ammo on.
 * If your dungeon is a good hike away from your base and not easily accessible, build a small outpost nearby and save yourself the hassle of running all the way back. If it's close enough you can pick up the fight right where you left off and not have to start over each time.
 * If you specifically desire to use the Minishark for the Skeletron fight, defeating the Eye of Cthulhu or the Eater of Worlds a couple of times to sell the Demonite Ore and Shadow Scales can be a very good way of raising the 40 gold needed to buy the weapon.

Specific strategies
Specific weapon/armor/arena combinations go here. nozaj_darkcasters strategy make a gladeater arena with three wooden platforms just big enogh to jump if you hold space if your lucky there will be a water bolt spell in one of the top bookcases take it close off everything but the door to avoid zombies comeing in (this involves backround to stop them spawning) and spam the water bolt at any part you wish to destroy it will bounce back and hit him again and sometimes will double or triple hit If you've already beaten skeletron once the expensive way (shooting stars or bullets) then you probably have all the dungeon goodies. Just go out with Shadow armor, muramasa, the blue moon, and the pheonix blaster with about 275 meteorite bullets. Spam the head and if he gets too close, take out the blue moon for lots of close combat damage.
 * budperson's Strategy: Skeletron without any hands is a joke. His head moves slow enough. Take out his hands with your weapon of choice. When he does his spinning head attack, walk on a smooth surface without jumping and cast as many Demon Scythes as you can, as he'll be lined up with you and aiming will be easy. They do enormous amounts of damage, and because of his large size will hit him more than once. When he floats above you stand still to regenerate mana. Jungle armor and Band of Starpower recommended.
 * Uglybad's Strategy: Phoenix Blaster w/ Silver bullets/Necro armor/Dungeon roof(smoothed out)
 * Octopus Baybee's Strategy: Sunfury / Night's Edge (for regular monsters)/ Molten armor / This works in any arena type, I don't even bother setting one up.
 * sinfire5's Magic Strategy: Starfury / Flamelash / Spam Spam Spam!!!
 * SnOwpanDAz's Strategy: Demon Scythe / Flamarang. Death Scythe has a few rotation that can cause multiple hits when the head of Skeletron is spinning towards you. Casting Demon Scythe as the head is going towards you will knock off a good 160+ damage on him, around 5 hits landing if done correctly.
 * MasterShizzle's absolute cheapskate minimalist strategy: Use either the Enchanted Boomerang or Flamarang for ammo-free killing, plus an arena with a lower ceiling to get the 'rang back faster. Ignore the arms, go straight for the head, and don't EVER stop clicking.
 * andy662's strategy: Molten armor / Fiery Greatsword / Demon Scythe / Water Bolt / Molten Fury + Hellfire Arrows / Flamarang / Space Gun / Obsidian Skull / Ironskin Potion / Harpoon / Restoration Potions / Phaseblade / 15+ Grenades. Fight in main dungeon entry building and bring your friends to the fight. Set spawn nearby.
 * Elengil's Strategy: With 1.0.6 out, it is VERY viable to go after the hands first. Once the hands are gone, he is SUPER easy, and even removing one hand helps loads. Shadow armor or Meteor armor are both VERY good options (If you have a Space Gun, DEFINITELY go Meteor) Keep to an open area well lit with torches and keep that mouse button down while avoiding him. (Using auto swing/shoot weapons of course, so you have one less issue to deal with as he IS pretty intense at the start)
 * BigMC's Strategy: Harpoon, Gold set (minimum), Ironskin potion, Featherfall potion, 2 Healing potions, Grappling hook. Smooth the roof down, then build a second level with platforms between each side, wait until it turns to night and use your ironskin, and featherfall potion, stay on the bottom floor of the arena as best you can, hunter's potion may be useful depending on the size of the arena, the Harpoon has an auto-fire, and it refires extremely fast up close. You stay on the bottom so that when he spins, you can jump over him using the above platform, try to stay as close as you can possibly be when he is spinning his head and you'll do crazy amounts of damage.
 * Xander's strategy: flamarang, spiky balls, shadow Armour. Throw a ton of spiky balls on a flat surface. focus on the hands and they die quick with all the balls.  kill hands then skeletron is no problem at all.
 * It's feasible to use an Ironskin Potion with a Thorns Potion to beef up your defenses so that Skeletron takes more damage than you do during collisions. If you have already beaten him before and raided a dungeon, add in the Cobalt Shield for maximum effect, but watch your HP. If not, alternate it for an Obsidian Skull to keep your defense up.
 * SuperGamerHero's Strategy: Space Gun, Ball-O-Hurt, Minishark, lots of potions. Start off by making as much of a flat surface. It helps when he attacks you with his hands. If you have Meteor armor, spam Space Gun as much as possible. If not, use Shadow armor and Minishark (you may use Space Gun, just make sure you have Mana Potions/fast mana regen, but Shadow armor gives more defense). Once the hands are slain, just spam attacks to his head (use everything you have if his head is spinning). He should go down in about 3 minutes using this strategy.
 * aRandomGamer's strategy: (NOTE: Unless the player as some skills and experience in the game it may be dificult to execute this strategy!) If you can easely dodge skeletron's attacks any armor should do, though if you fight with the starting max life, the best armor at hand should be used. As for weapon, around 500 shurikens are enough if you don't have better weapons. If using shurikens, the best place to fight skeletron is a wide flattened area. This setup allows "low level" players to kill skeletron early on, though it's kinda pointless since the Dungeon has a quite higher equip requirement. Still, if going for skeletron from the beginning, just follow this setup and first aim for his hands. They go down really fast and make skeletron almost harmless due to it's slow attack speed.
 * Longbow73's Strategy: Flatten out a flat space with enough room to run around. Make sure you use solid blocks and not wooden platforms. As the fight begins, spread Spiky Balls all over the floor and let his hands run into them, killing themselves (Assisted Suicide!).  Use your weapon of choice, preferably a ranged one, to kill the head.  Skeletron's head is super easy to kill when you don't  have his pesky hands poking you the whole time. Shadow armor or better is recommended.  I use the Star Cannon, but it may be difficult to find enough stars. I always run around at night, and so I quickly amass many MANY fallen stars.
 * Deltalon's Strategy: Have AT LEAST Shadow armor, a Musket, and 250 Musket Balls. Clear a large flat area and scatter Spiky Balls. Use the following buff potions: Ironskin, Thorns, Regeneration, Shine, Night Owl.  Focus on his hands until they fall, then shoot his head.  A Phoenix Blaster can do the same job as a Musket, but faster.
 * MadmanMario's Strategy: Flatten a fairly large arena. Equip the Night Armour set and the War Axe. Use its moonwalking capability to just keep going. Equip regeneration bands or movement increase accessories if you want, although a defensive accessory is more advisable.
 * Giwtem's Strategy: Make a flat arena, drink ironskin, regen potions and soup. Meteor armour or better. Spam Minishark with meteor bullets, about 500 should do.
 * Piroton's Strategy: Get a Minishark and at least 350 health, along with 500-700 Musket Balls. Use with Molten Armour + Rocket Boots + Obsidian Skull + Ironskin Potion + Grappling Hook + Regeneration Potion + Bowl of Soup : Fire at the head and only the head. Use the grappling hook to prevent any fall damage; use the rocket boots to keep you dodging his attacks. With a Healing Potion or two and reasonably good aim, you should be able to take his head out completely without suffering much damage. Works best with 400 Health, and you will most likely completely annihilate him with ease. His hands are reasonably easy to dodge, especially with Rocket Boots.
