An Arena is generally an area that the player builds where they can face a Boss or other significant challenge more easily. Each arena can be different for each boss, some consisting of a flat area or multiple layers of Platforms supported with Statues.

General Arenas[edit | edit source]
- An arena is better built away from Bases so NPCs won't get hurt or killed. It's better built near the ground, far from Space so there won't be any unwanted or spawns during an important fight.
- A typical arena usually consists of multiple long rows of , or a flat surface on the ground or the air made out of to greatly increase running speed.
- Sometimes, the shape of the arena depends on the Boss or Event and how the player decides to fight it. King Slime and Golem lack the ability to attack through solid blocks. and can be used to easily kill enemies from Events, while certain bosses like
- Placing Mana more easily. , , placed in and will greatly increase Health regeneration in battle. A Mage may also want to place and to regain
- reduce enemy spawn rate, which may help on bigger arenas.
- You can build a house for your NPC near your arena. The House should have a , so in the middle of the battle you can use a or to visit the Nurse and get instant healing. The house is better built away from the arena to prevent the Nurse from being killed.
- Once you have killed a Mechanical Boss and had the move in, you can buy and use to devastating effect. When wired to a placed above them, you can instantly transport across the arena as soon as you walk on them, greatly increasing mobility. They could also, alternatively, be used to teleport to the Nurse, heal up, and quickly return to the arena.
Bosses[edit | edit source]
- See also: Guide:King Slime strategies
This content is transcluded from Guide:King Slime strategies.King Slime is one of the few bosses in the game that lack the ability to go through blocks. This can be exploited in multiple ways:
- On Console version and Mobile version, climbing on a 35 blocks above the ground allows you to attack him at range safely without him teleporting onto you. Add extra rope to give yourself a margin of error, or to retreat and heal if need be. Using this method makes potions, higher damaging weapons, armor, and movement accessories optional, as the player will not need to dodge attacks or mitigate damage. In Desktop version, this exploit will not work.
- Make one or two platforms above the ground; King Slime will eventually teleport to ground level and you can easily hit him from the platforms.
- A flat area with small room below it with Platforms as roof for the player. King Slime can't enter small rooms and thus cannot reach the players in it.

This content is transcluded from Guide:Eye of Cthulhu strategies.
An arena for the Eye of Cthulhu should be large enough to dodge and maneuver around in. The recommended size is just about the size of the screen, as the boss does not require a lot of mobility.
The simplest arena design consists of multiple rows of wooden platforms to have more room to jump and dodge. As the fight will be at night, add torches to improve visibility. Remember to adjust the distance between platforms depending on your jump height (this is 6 tiles at minimum, depending on which accessories you have), and consider placing some ladders (with platforms or rope) to aid your vertical movement.
Another design is a long, completely flat surface. This allows you to dodge the Eye by running to the left or the right with Swiftness Potions or Hermes Boots.
- See also: Guide:Eater of Worlds strategies
This content is transcluded from Guide:Eater of Worlds strategies.
The Eater of Worlds is a very large Worm enemy, so dodging it may prove to be difficult. You may want to try fighting it on the surface instead of underground. If summoning this boss via breaking shadow orbs, be sure to provide yourself a quick and safe escape back to the surface where your arena will be. A room with a Bed next to your arena can let you teleport there easily, but be careful that the path from orb to arena does not go through any non-Corrupted areas (lest the boss despawn). When making your arena on the surface, you have some options:
- In Normal mode, make it fairly tall, thin, and easily climbable with many Platforms. That way, not only you can see it coming, but this will force it to climb in a relatively straight line, leaving large portions of its body exposed, and vulnerable to piercing attacks.
- In Expert mode, due to the frequency of the Vile Spit attack, the Eater of Worlds will become much harder to dodge. You need to make an arena to compensate for this new attack. Build a regular row of platforms (your choice of length) in the sky. After this, build a long row of blocks (at least 50 blocks long) next to it. While you fight the boss, all of the Vile Spit projectiles will be blocked by this block barrier. If you built the arena low enough, the boss will be able to travel on your defense platform-- Watch out for this, but also utilize it to attack it when it's vulnerable.
- Whichever option you choose, make sure the arena doesn't go too high. If it goes too high and the Corruption background disappears, the Eater of Worlds will start despawning.
- It's also not recommended to build your surface arena above a valley. While it's still above the ground, the hills on either side will provide higher ground for the Eater of Worlds to get to you and make your arena less effective.
If you don't want to fight it on the surface, it's alright to fight it underground instead. If you are breaking Shadow Orbs, hollowing out an entire arena every third orb or escaping to a surface arena may not be practical; you should modify the terrain around you to have a quick path of escape to a space with good horizontal clearance and any hazardous terrain smoothed out or boarded over. Consider placing platforms periodically to provide extra maneuverability.
If you have a Pre-Hardmode Autoswing weapon such as the Falcon Blade or a Katana, you can use a Grappling Hook and hook it to the ground to be able to remain stationary. Alternatively, a Cobalt Shield or an Obsidian Shield can be used to become immune to Knockback. If you happen to have any Shadow armor, it could be useful, as it increases your melee speed. Once the Eater of Worlds has been summoned, begin swinging. As the Eater of Worlds tries to inflict damage by passing through you, the Autoswing weapon will destroy its sections fast and effectively, and the fight will be over fairly quickly. This can also be used as an effective farming technique.

Your arena will have to be built in The Crimson, because it can only be summoned there. Since the Brain of Cthulhu spawns as soon as you smash a third Crimson Heart, you're likely to be in a very enclosed area when the fight begins. This can lead to you to being swarmed by the Creepers and get overwhelmed. This can be avoided by preparing the chasm's main chamber as an arena beforehand, and choosing which Hearts to break first:
- For the first two, pick the least convenient hearts (distant, above the main chamber, underwater, etc).
- For the third, pick the closest to the main chamber, toss a Bomb or another explosive and quickly go to your arena while it falls.
If summoned with a Bloody Spine, then the arena can simply be made in the Surface, however do not make it very tall, as jumping too far above it will be considered exiting the Crimson, causing the Brain of Cthulhu to despawn.

This content is transcluded from Guide:Queen Bee strategies.Even if you summon the Queen Bee by breaking a Larva, you do not need to stay in the hive to fight it - you can get out of the hive and fight it in the wide-open areas of the Underground Jungle if you'd prefer. However, most Hives offer an easy arena: a decent amount of space is already carved out, and the pool of Honey at the bottom provides a health-regenerating buff which stacks with other buffs.
As with most bosses, Wooden Platforms are vital. Having them every 5 blocks is an optimal height but if your jump height is boosted in some way, you can increase the number of spaces between platforms which can save you materials.

Warning: Don't make significant edits to the dungeon floor. Doing so can stop the Endgame Cultists from spawning, potentially blocking progression. Plan your arena above the Dungeon roof instead.
The entrance area to most dungeons can often be modified into a more desirable arena if needed. Most important is that you have room to dodge the hands, as well as enough vertical space to avoid getting trapped when Skeletron's head begins to spin.
- See also: Guide:Wall of Flesh strategies
This content is transcluded from Guide:Wall of Flesh strategies.The Wall of Flesh benefits from having an arena prepared more than other bosses.
The simplest arena is a long bridge of about 750 blocks with some space above it for the player to maneuver. Placing the player out of danger from falling into lava and ensuring that they can keep a steady pace of progression allows the fight to go quickly and smoothly. Players may also wish to place lights and make holes to drain Lava from Lava Slimes along the bridge; alternatively, Obsidian Platforms can be used, as they do not break when contacting lava, and the materials to make them can be obtained in bulk by demolishing the Ruined Houses.
Note that Underworld map generation tends to place Ruined Houses towards the middle third of the map, leaving the eastern and western wings mostly clean.
The Wall of Flesh begins its attack from whichever side of the Underworld's map edge you're closest to. This allows you to control its direction of approach. Fight in the direction you're most comfortable with.
Killing the Wall of Flesh will generate a bricked-in treasure box above your bridge. The bricks can serve as kill-markers, but they may interfere with movement if your next fight runs close to that spot.
Alternatively, you can build the arena with, because you can keep a safe distance with a with decent speed.
- See also: Guide:Destroyer strategies
Using a Daedalus Stormbow with holy arrows can be extremely effective due to the destroyer's length making it easy to hit
This content is transcluded from Guide:The Destroyer strategies.Like with the Eater of Worlds, a tall, wide arena with multiple rows of Platforms can make dodging its main body easier.
Alternatively, standing on a rectangular box around 150 blocks into the air will make the Destroyer unable to reach the player while also protecting them from its lasers, leaving only the Probes as a threat. However, the player should be careful about building the box too high as Harpies and Wyverns may start to spawn.
Additionally, running along a long platform with plenty of campfires and sunflowers is a viable strategy, as all off screen air blocks are treated like solid tiles to the Destroyer. This also allows you to more easily dodge his lasers if they are behind you, and using the mini map can help you see where he may pop up next.
- See also: Guide:The Twins strategies
This content is transcluded from Guide:The Twins strategies.The Sky above the surface is highly recommended for the Twins arena, as vertical movement is required to dodge most of the attacks.
- A very long Sky Bridge (if possible made out of or ) is optimal. Continuously running with / / / causes both to miss you with their projectiles very often, and keeps each Twin at a stationary horizontal position most of the time, allowing you to fire continuously at it without switching your aim. Wings will help dodge each of the Twins' second phases. Using Asphalt can negate the need for Boots, while using them can allow you to avoid taking damage completely. However, try not to run too fast if you use Boots and Asphalt, as Retinazer may fall behind and despawn. Spazmatism, however, is fast enough to keep up. Regular stone blocks can be used too if you have obtained the .
- The standard Boss arena of several layers of Platforms may be of use, as it allows firing and maneuvering in any direction. A solid ceiling just above your top platform will block Retinazer's beam attacks, as Retinazer always flanks from above.
- Also, a wall on both sides of a small area can block Spazmatism's cursed fire, but be careful not to run out of time from covering behind the wall. It is helpful to have a one block hole one block up to shoot through. This is more useful if you want to try tanking the boss with the above tip of heart statues. If you can tank the hits with the help of heart statues, you can gun down Retinazer while Spazmatism is only able to charge at you.
- A safety box in the ground isn't bad either, if you acquired the . That way you could attack Retinazer while its laser can't hurt you in the box. In order to attack Spazmatism make the box one block from the surface and bring , the impact from the stars could hurt it. Stay close to the edge so the Cursed flames can't hurt you.
- See also: Guide:Skeletron Prime strategies
This content is transcluded from Guide:Skeletron Prime strategies.As with all bosses, an arena made out of Wooden Platform or Minecart Track greatly increases your mobility, and it will also moot the Prime Cannon. You will want several rows of Platforms, each around 50 or so blocks long. The platforms should be suspended off the ground to prevent the Prime Cannon's grenades from detonating too close to you. A solid ceiling should be avoided since Skeletron Prime will often retreat a fair distance when not using his spinning attack.

This content is transcluded from Guide:Plantera strategies.Bring a Hammer to remove the jungle walls so that in Plantera's second phase, the hooks can only grapple on to the blocks so she cannot reach you with her hooks, and thus you will not take damage from them.
Golem[edit | edit source]
- See also: Guide:Golem strategies
This content is transcluded from Guide:Golem strategies.
- Create a small wall dividing the entrance and the arena, leaving an opening for your projectiles to get through. This becomes difficult to build if your default layout has the entrance in the ceiling.
- Create a much larger wall that divides the arena on either side of the altar leaving an opening at the top for you to leap through post-spawn and a spot for your weapons.
- An assortment of small walls scattered throughout the arena.
- A small pit that you can leap into while Golem stomps and punches. This will allow you to deal heavy damage, but you have to be cautious about his eye lasers and fireballs. A heart statue in the pit with you can be useful in keeping you alive.
- can be used for dodging the attacks and move safely and instantly from side to side.
- If you decided to fight Golem in the temple, then and would be useful because they will still keep spawning during the fight. It'll be much easier to get rid of them.
For safety reasons, you should use a Pickaxe or Wire Cutter and remove/disarm all of the traps, as these can be hazardous in the fight.
- See also: Guide:Duke Fishron strategies
This content is transcluded from Guide:Duke Fishron strategies.The Arena must be located in the Ocean, unless you're very confident that you can beat an enraged Fishron, which is usually not recommended.
- Make an arena out of . It should stretch at least across the ocean. Make it 3-5 platforms high; each row should be at least 20 blocks away from each other. Leave a gap at either side for maneuver, however.
- The Arena must be very tall: the Tornadoes are very tall, and thus, it requires significant amount of flight time to go to the other side of it.
- See also: Guide:Lunatic Cultist strategies
- See also Guide:Moon Lord strategies
This content is transcluded from Guide:Moon Lord strategies.If one is having problems fighting the Moon Lord, a skybridge can be built to make the fight significantly easier. Ideally, it should extend quite far from either side of your spawn point (700-1000 platform blocks should suffice). The Moon Lord will not despawn unless all players are dead, meaning you can outrun him and heal for a while if need be. However, straying too far will cause the Moon Lord to teleport on top of you, so careful spacing is required. This is of less concern in multiplayer, as the Moon Lord will only chase one player at a time, giving the others time to retreat and heal up if necessary. A long straight Minecart Track paired with the Mechanical Minecart will help you avoid most of his attacks. Make sure to hammer the ends for bumpers or make a loop to return to the straight track.
1.3.5 or earlier: A simple roof made of solid blocks is useful for blocking the Phantasmal Deathray. Thickening the roof will also mitigate the explosions of the Phantasmal Eyes. You can open up holes in the roof to shoot through when the Deathray isn't active, or you can leave the roof without any holes and damage the Moon Lord exclusively with weapons that can phase through walls. In 1.4, the Phantasmal Deathray will pass through blocks and damage the player below, vastly reducing the effectiveness of this strategy.
Asphalt can still be used to dodge the tongue if you value the ability to use Vampire Knives. When the Moon Lord teleports with his tongue already chasing you, the tip of the tongue will not teleport with him. This allows you to completely outrun the tongue, avoiding Moon Bite and allowing Vampire Knives/Spectre armor to work normally.
- See also: Guide:Dungeon Guardian strategies
This content is transcluded from Guide:Dungeon Guardian strategies.You need to be in a world where Skeletron has NOT been defeated. Otherwise, it will not spawn.
As it will instantly kill you when it touches you, the only way to defeat it is to outrun it. Therefore you have five good options for terrain:
- The first option is simply use the whole map, by using Gravitation Potions to move around. You will fall faster than it and you can move diagonally to go even faster.
- The second option is a very long Skybridge. You will be equally fast as the Dungeon Guardian when running horizontally and jumping with wings. If you want to outrun it make a diagonal skybridge or build the skybridge out of Asphalt.
- The third option is to simply use a good pair of Wings or a flying mount such as the Cosmic Car Key or Shrimpy Truffle with a clear, open space.
- The fourth option requires a rail system that goes in a circle, using a fast Minecart (Using mechanical Minecart is more useful) or Booster Tracks. This can also be automated with Traps, such as Spike Ball or Spear Traps within the rail circle of with summons and a Star Wrath.
- The fifth option is to set up a Hoik loop. As the Dungeon Guardian spawns use a recall potion to get to a spawn point set up near the Hoik loop and mount it. If timed correctly, you will loop around fast enough to make the Dungeon Guardian constantly change direction, and, as a result, simply spin in tight circles in the center of the Hoik loop.
To reliably "summon" the Dungeon Guardian, it is recommended to dig a straight shaft down from outside the dungeon. The Depth Meter is recommended for this.
If the player has access to the Mechanic and Steampunker it is possible to build a Teleporter arena (example). This can make the fight dramatically easier, especially if the Teleporters are automated with Timers. As the Mechanic is found in the Dungeon it is required for the player to bring materials from a world where Skeletron has already been defeated.
Invasions[edit | edit source]
General Invasions[edit | edit source]
- See also:Guide:Defending against events
Before starting an event, make sure NPCs are protected, otherwise they will be attacked and possibly killed during the fight. Placing a block in front of a Door will prevent enemies from forcing them open and killing the NPCs.
If defended properly, the events can then be easily fought on a player's Base, using the Houses built as cover. Since most enemies from invasions lack the ability to attack through walls, they can be easily killed while standing above them in an enclosed room. However, make sure to have an exit ready for when the enemies that can attack through blocks spawn.

Before facing the event, making a completely flat arena works very well. If an enemy's path to the Eternia Crystal is blocked it will phase through obstacles, so trying to stop their progress with blocks won't be very effective. Building the floor with Potions is always a good idea, while it is also good to place , , and to survive for longer. When fighting Tier 2 and 3, building a ceiling above the Eternia Crystal will protect it from Kobold Gliders, since they explode on contact with blocks.will greatly increase movement speed. Using
Moon Events[edit | edit source]
A flat surface about 168 blocks wide (See NPC spawning) will focus all spawns on the arena. Above it there should be a long platform of the same width, high above the ground in order to keep the enemies out of Melee reach. Since the player will mostly focus on the Bosses on the later waves, it's a very good idea to support the arena with a Lava pit and Traps to take out the weaker enemies more easily.
and can potentially cover the entire arena, while and should be placed at the Lava pits to make full use of their limited reach but high damage.
It's also a good idea to make a room with anear the Arena, so in case of death you can quickly get back to it.
