（==標準競技場== 每個玩家都應該有的東西是一個適合可召喚 Boss 的競技場，並可修改以用於對抗特定的 boss。此部分會引導你做這些步驟。
- 主結構。競技場的形狀取決於 boss 以及戰鬥方式。您可以參閱具體 Boss 的建議。典型的競技場都有治療站和戰鬥場，無論其形狀是矩形，直線形或另外的形狀。不妨將競技場用物塊圍起來，這樣可隔絕野怪。
- 治療站。你可能需要為更加強大的 boss 配備治療站。治療站指可以加快生命回復的小區域。任何治療站都應處在溫馨的篝火之中(即其對應增益)。在角色的最高血量達到 400 之後，收集生命水晶並做一些紅心燈籠掛在治療站附近。造個寬 3 格高 1 格(內部尺寸)的淺池子，然後注進蜂蜜。踩進這個池子就會給你 30s 的偉大再生 buff。Heart Statues效果更好(儘管更加稀有);每次使用可以恢復多達 60 生命值。把雕像連接到一個5秒計時器，就會每 10 秒吐出一顆心。如果有兩個心形雕像，確保至少相距 20 格，否則雕像使其只能堆積起 3 顆心。如果你有三個及以上紅心雕像，就需要至少 50 格。戰前請確保打開計時器。如果需要魔力，你也可以在星星雕像身上做一樣的事。
- 護士站。你可以給你的護士 NPC 在競技場裡或附近建間房子。戰鬥中途，你可以與她交談並接受即時治療。您也可以考慮把她的房子造成只有三格寬（同時很高），以便更容易地找她。即使必須建造天花板，牆壁和帶平台的地板，您也無需進入房屋即可治療。如果房子的四壁用實體方塊砌成，又用方塊堵住門外，護士就能活得更久。也請記住看對話框時，戰鬥是暫停的。你可以在上利用這個有利條件。只需跑到護士站旁邊按下Esc(在自動暫停啟用的前提下會停止時間流動），然後從容不迫地把光標移動到護士的身上，再次點擊Esc按鈕並立刻右擊護士。獲得治療後，把光標移到你想攻擊的地方，比如說對着boss，再點一次Esc，然後馬上投入戰鬥。這個步驟可以避免在你被打的時候死亡，並且可以直接右擊護士回血。
- 攻擊區。這是你準備過的地方;你料到 boss 會來這裡，你就在這裡攻擊它。一種攻擊區是監視 boss 到來的監視點，並從這攻擊它——無論是近戰，遠程攻擊還是魔法攻擊。這個監視點可以同時是一個治療站。您也可以考慮在一些這種點四周放方塊以保護你免受boss傷害。另一種攻擊區是你設置的傷害？(damage-dealing)Trap。詳見這個部分。
- 傳送設備。一經機械三王被打敗，同時朋克商人搬來了，你就可以購買和使用傳送器來製造壓倒性的效果。您可以用其連接兩個及以上治療站或者進出你的護士站。當Boss 靠近時，踩在傳送機上，立刻傳送穿過競技場，然後攻擊；而不是花時間在與 Boss 保持距離上。
有些人可能會放棄屋頂，把競技場暴露在天空中。理由是有小几率墜星會剛好打中眼球，就會造成 999 傷害。這大大簡化了戰鬥，即立刻殺死克蘇魯之眼。
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. Walling the area off might also help exclude any minor enemies from joining the fight.
Ensuring the floor is nice and flat will also allow plenty of time to take advantage of the Skeletron's spinning attack, as its defense is set to 0 while using that attack. It may also be a good idea to bring along any Spiky Balls to set on the floor, if you have any from fighting the Goblin Army. When Skeletron begins his rolling attack, he'll roll right over them and take the full brunt of their damage. Also they will be useful for killing his hands just leaving his head.
A simple, effective, and time-consuming approach is to build a Sky Bridge with Minecart Tracks. Then spawn Skeletron, hop in your minecart, and speed away. Skeletron will chase after you but will not catch you. Kill it with ranged attacks. If you run out of tracks before you kill it, die, and add more tracks before you spawn it again.
Location is important for this arena as well. The goblins will naturally target your initial spawn, that is, the center surface of the map. So no matter what you actually have there, that's the general area where you will encounter goblins when they arrive. You may as well prepare a proper greeting for them.
Make sure there are no NPCs in this area, as they will be attacked and possibly killed during the fight. Goblin Sorcerers' attacks go through walls and they can teleport indiscriminately, so the only defense is to make sure that your NPCs are not nearby.
Flatten out an area and make sure that there are no pits or jumps. Walls are not necessary, as during an invasion the newly spawned monsters are the target rather than a distraction. Make certain that any platforms or areas can be easily and quickly reached from anywhere else on the screen, since most players will be looking to quickly close in on casters with their melee weapons.
Another way you can kill the goblin army is to set up a flat arena in your spawn point, and set up staircase walls on either side. When the goblins start to come, fire a Water Bolt at both sides, and they will continue to bounce back and forth, killing goblins.
1.3更新後就不能夠利用史萊姆王的大體積了，因為他現在可以傳送到你的位置。不過這個boss通常都很簡單，你不需要準備場地。在空中掛二三十根繩，然後向下遠程攻擊即可。任憑他跳斷腿，他就是無法傳送到你身上。為了打敗他，有必要讓繩子長於他的跳躍距離。Both he and all slimes he creates will be defeated by this easily.
The Wall of Flesh, more than probably any other boss, benefits from having an arena prepared before engaging. Even experienced players wishing for a quick fight should ensure that the path behind them is clear before summoning it. A full arena can speed up farming this boss, which can provide the player with several weapons and accessories that are valuable even late in the game.
最簡單的場地就是鋪長約 750 格的一條橋，並在上方留出機動的空間。防止玩家「赴熔蹈岩」，保持玩家的穩定前進速度，那麼戰鬥就會快速而順利地進行。人們也會沿橋放置光源，或者在上次打死肉山的地方做記號。
Note that Underworld map generation tends to place Ruined Buildings towards the middle third of the map, leaving the eastern and western wings empty aside from Ash, Lava, Hellstone, and plenty of enemies. Lava topography also tends to level out at either end of the screen within a ten-block height variance.
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. The minimap on the right side of the screen can interfere with visibility on the Wall of Flesh at times. Fighting west-to-east may be easiest, though once you are familiar with the mechanics the direction won't make a large difference. Fight in the direction you're most comfortable running.
Given all the above, an optimal Arena can be made by creating a long Ash bridge starting from one side of the screen and running long and flat for a distance of 500 to 1000 blocks, depending on your damage output. Going from the edge of the map to the first Ruined Building you see will give you a sufficient platform, but on a Large map that may be a punitive amount of construction work for the player. Wooden Platforms are not useful in this fight as the Wall of Flesh will constantly orient to the Player's position
Clear any Ash up to three blocks above your bridge (standing overhead swing height) so you have room to jump occasional lasers. Level any Ash hills in your way and drain lava appropriately. It is very difficult to run out of Ash - Players should feel comfortable using explosives to create retention pools and drainage channels.
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 also interfere with jumping if your next fight runs close to that spot. The bricks can be mined for your collection to keep a clear Arena.
A way to quickly take out much of the wall's health is to travel to the very edge of the map in The Underworld and place some explosives where the wall will spawn. Wire them up to a lever (from a safe distance!). When you throw the Guide Voodoo Doll into the lava, wait for the wall to be directly on the explosives until you pull the lever. This will deal roughly 250 damage per explosives.
Your Eater of Worlds arena should also serve as an arena for fighting The Destroyer (However, moving the walls and ceiling in may protect you from of The Destroyer's lasers). The same types of visibility and movement are needed for both fights. The Destroyer does not need corruption present to be summoned.
Alternatively, you could start by building around 250 feet into the air. Create a large rectangular box at the top. Destroy the tower you built and replace it with Rope. The rectangular box should be around 5 blocks high, and 20 blocks wide. have 15 of the blocks on the left side made out of platforms, and the rest made out of solid blocks. Pour honey into the solid blocks. This area will protect you from The Destroyer's lasers and give you some regeneration. You can also place Campfires or Heart Lanterns to increase this effect. Once this is all done, the fight should be relatively easy. Using a Nimbus Rod and Golden Shower will prove to very useful, even though The Destroyer is immune to the Ichor Debuff. If you did not build the arena high enough, and the Destroyer can dig its way into it, increase the height because not being able to be hit by The Destroyer's direct attacks is essential to an easy win. All you will have to do during the fight is make sure there are always nimbus clouds, fight off Probes, and fire your Golden Shower. If you need, you can make suitable housing for the nurse to move in for her healing, and the dryad to move in for her dryad's blessing buff. These are both very useful.
Or, just stand in the middle of your Eye of Cthulhu arena, with a cobalt, obsidian, or Ankh shield equipped, and repeatedly hit in one direction with the mushroom spear, and if you start losing health, fly around until you have it back.
打之前最好建一堆平台以便移動。打時先集中火力射殺Spazmatism。因為其攻擊傷害巨大，且施加Cursed Inferno減益。也可以先幹掉一隻再打另一隻。主次不分明會在第二階段大大提升難度。凌空造橋也是搞定它的不二法門，而這種方法關鍵在於機動和速度。Using crystal bullets with the Uzi or Megashark will prove to be very effective. To increase this effect, using the Golden Shower along with this will increase the damage, as The Twins are not immune to the effects of Ichor. If you opt for fighting The Twins on a sky bridge, placing wired heart statues in consistent intervals can make the fight a cakewalk - you will dodge many of The Twin's attacks, and whenever you get hit you can just pick up your hearts whilst you run along your bridge. The best material for the sky bridge is asphalt, if available. If you keep running along an asphalt bridge, the Twins will almost never hit you. Using wings to fly around them at the end of your bridge is a very good idea if a full bridge is not available. This will make The Twins one of the easiest bosses in the game, as you will be nearly invulnerable.
Building an arena for fighting Skeletron Prime can be a little tricky. Simply using Gravity Potions and fighting in the sky may be more effective. A long bridge may also work. (Use the arena for the twins if you have one) The explosive only detonates on solid blocks so using some wood platforms as well will keep you from exploding. A megashark or an uzi loaded with Ichor Bullets is another extremely effective way to defeat it.
An effective arena for the Golem would be to square out and level the room that the Lihzahrd Altar is in and use wings to fly around and dodge his attacks (mainly magic and ranged users). While exploring the Lihzahrd Dungeon, you can gather all the traps. Construct vertical pillars out of traps large enough for Golem but high enough for it to not get out on both sides of the altar. Finally line the ceiling with Spiky Ball Traps. After summoning Golem, leave the enclosure and repeatedly activate traps to help fighting Golem (Be careful for the spiky ball traps, as they still hurt you) Also, using weapons such as the Death Sickle or the Mushroom Spear are useful, as if you make a walled-in arena, you can hit it through the walls (The Staff of the Frost Hydra could also be used).
Alternatively, simply destroying all traps in the area and using a Golden Shower or Vampire Knives will work, essentially assuring that you will not pass beneath 400 health. Agility is a main ingredient in using this strategy. Also, if you have it, USE THE MAGNET SPHERE! Go to one side of the Golem and fire towards the other, and you will deal about 400 damage per sphere.
造一條長走廊，最好高約六格，寬 100-200 格，末端各有一傳送機。召喚出世紀之花後，讓它穿過走廊，然後跑到邊緣前往傳送機。When Plantera charges after you teleport to the other end of the hallway and shoot down the hallway, with some sort of non-arced, high velocity weapon, such as the Megashark with either cursed, or crystal bullets. Adamantite, Titanium, or Hallowed armor is suggested for this fight, with no preferred accessories. Repeat this process until Plantera has been defeated.
造一座跨海大橋，就可以刷海洋敵怪了。刷海怪是刷海盜地圖, key molds, 熒光棒, 鯊魚鰭, 黑墨水，以及顯而易見刷錢的好辦法。你也可以造兩層平台，第一層在水下兩格的地方;第二層在水面。同時你站在第二層的一個小水池裡面，讓所有敵怪往上朝你游，用意在使水怪從水中跳到平台上。The Spider Staff is good for automatically killing the mobs as they obediently stay out of the water and is very easy to obtain. Another way to kill them is by connecting one-second timers to Spear Traps or Spikey Ball Traps from the Lihzarhd Temple. It is recommended to put mushroom grass mud in a large square above the ocean. This will cause Fungo Fish to spawn.
Attempting to enter the dungeon before killing Skeletron will greet you with the most powerful boss in the game: The Dungeon Guardian. It deals a whopping 1000 damage, which generally ensures death for most players. Touting an impressive 9999 Defense and Health, the guardian will take a measly 1 damage from anything you throw at it (except for criticals, which deal two). Basically, the only way to beat it is with a ton of patience and some decent evasion skills. For preparation dig out the top of the dungeon and make mini-house (it must be valid housing, i.e. able to house an NPC) to the side of it. Place a bed inside and use it to set your spawn point, allowing you to quickly return to try fighting should you meet your demise. Dig a relatively wide vertical-tunnel in the top of the dungeon (directly above the shaft into the dungeon) to allow easy escape once the guardian has spawned.
Despite what most say, Turtle Armor does not deal 1,000 damage. Turtle armor does half the damage you take back to the enemy, and then the enemy reduces the damage with their defense. This makes the Turtle Armor effectively only deal 1 damage to Dungeon Guardian, so it is not recommended. Spectre armor will not be of much help, for healing will not be required due to instant death, and damage will not be increased. Shroomite armor is recommended, the reduced ammo usage of the ranged set helps tremendously. Bring a Chain gun (reforged to rapid) with a TON of Chlorophyte or Crystal bullets (above 10,000 is necessary). For accessories, have all of them reforged to Lucky (+4% crit-chance) as it will increase your DPS tremendously. Bring a Black belt or Master Ninja Gear, as the 10% dodge chance may potentially save a run. Other recommended accessories are Lightning/Frostspark boots and Fishron Wings for optimal mobility. Potions should include a large number of gravitation potions and a couple ammo reservation potions. Use an ammo box before you begin the battle for maximum ammo-efficiency.
First, drink a Gravitation Potion or use a Gravity Globe (Moon Lord Expert Mode drop.) Drop down as far as you can into the dungeon without the guardian spawning. The second that you see guardian spawn, press up once using the Gravitation Potion or Gravity Globe, and escape through the hole you made in the top of the dungeon. Kite the Dungeon Guardian around, making sure to keep a reasonable distance from it. Aim in its direction and fire your Chain Gun at it. Make sure to keep track of where the guardian is at all times. If you are using a Gravitation Potion, make sure to re-use one when it runs out. Repeat this until the boss dies. Another thing you can do is set up a hallway with spiky ball droppers all along it, wire it up to a 1 second timer, and set up teleporters to either blocked-off end of the hallway. Jump into the hole, and then go back up to the hallway, and start teleporting back and forth. It might take a while, but eventually it'll die.
- Leave campfires, heart lanterns and heart statues linked to adjacent pressure plates in order to have improved self healing during the fights.You can also make a honey lake with platforms on top so you can just hop down for a quick regen. You can put your pressure plates (Above & Below) in the lake.
- Make a house close to the arena and move the nurse there and then set it as your spawn point, that way you can use the Magic Mirror to escape from a pinch and get some healing then return to battle.
- A good way to regain full health is to build a house for your nurse and put it away from your arena, and connect your arena with the house with a teleporter and when you are on low health during the battle, you can teleport to your nurse's house to buy a heal and teleport back to resume the battle. (Be careful as building the house too far away may cause the boss to de-spawn)
- You could even add your unwanted dart traps on the side linked to pressure plates for extra help in battle. A good idea is to link them to the same pressure plates that your heart statues are linked to. Players in later stages of the game can loot the Temple for super dart traps, fire or spear traps to use.
- As an alternative to pressure plates, you can use a timer to create piles of hearts and mana stars that you can collect once in a while. If you have multiple statues, you could build several stations within your arena.
