- 通常打 Boss 我們需要一個大而平坦的表面，使得有足夠的操作空間。考慮到地牢守衛的超高攻擊防禦值與血量，若與它接觸，則幾乎百分之百能瞬間秒殺掉你，你最好的應戰方式就是逃脫它。因此對於地形的準備，你有兩個較好的選擇。第一種方法是單純使用整個地圖的空間，通過使用重力藥水快速地移動。你將會比它更快地墜落，且當你斜向移動時速度還能更快。第二個選擇是修建一條非常長(單層)的天橋(天橋)。你可以設法使得自己在天橋上水平奔跑和用翅膀跳躍時和地牢守衛一樣的快。為滿足當你想從它的攻擊下逃脫時的需要，應當修建一個斜向的「天梯」(使用除平台以外的任何物塊)或建造瀝青的跑動天橋。
- 也可以通過使用 冰雪塊製作一個大型的快速道，使用溜冰鞋或霜花靴快速移動
- 高射速的遠程武器有類如鏈式機槍、鱷魚機關槍、巨獸鯊、迷你鯊、太空海豚機槍、星旋機槍和烏茲衝鋒槍等。把他們與水晶子彈配合使用可以造成更多的額外傷害，使用葉綠彈和鏈式機槍也可以以瘋狂的速度造成巨大傷害。由於在攻擊時，任何武器造成的傷害都會被歸結為 1 或 2 Hp 傷害所以使用攻擊速度更快的武器會很有幫助。切記一定要帶上足夠的彈藥，可以認為 2 滿組的彈藥是最低的攜帶限度，不要忘記無盡火槍袋在這種情況下是非常有用的，最好也帶上。
- 可能有用的弓是海嘯或脈衝弓，因為它們會發射多個箭。 將它們與聖箭或心箭結合使用會造成更大的傷害（如果您不使用天橋方法，則會很有用）。 如果玩家碰巧進行了月亮事件，毫無疑問，「幻影弓」將成為主要的弓，因為它能夠發射連續的箭，並且有66％的機會不消耗彈藥。 將此弓與聖箭或霜凍箭一起使用是一個不錯的策略。
- If you are playing with friends, take the Dungeon Guardian to spawn and fly in circles while attacking with Vampire Knives and let your friends use the Scourge of the Corruptor and blast tiny eaters at it.
- If using Minions you can use the 星塵細胞法杖 or 星塵之龍法杖 to do lots of damage while the player concentrates on dodging.
- Any bow that has higher damage than a 銀弓 or a 鎢弓 using 心箭s, because Heart Arrows will stun the Dungeon Guardian, giving you time to maneuver.
- 宇宙車鑰匙 and 種子彎刀 are a great choice to defeat the Dungeon Guardian, since Seedler will throw explosive seeds. It will take around 5-10 minutes if you yourself don’t miss too many hits on the Dungeon Guardian.
- 使用重力藥水、幽靈靴亦或是閃亮紅氣球，當然也可以是這些飾品的升級版本。 These will be needed when you reach the end of the skybridge to jump over the Dungeon Guardian when switching direction. 此外，玩家需要能夠使奔跑達到水平移動速度上限。
- If you do use a 重力藥水Gravitation Potion, an item to negate fall damage or provide running may still be useful.
- If you use any type of wings, the 蛙腿 is very useful because it provides 50% increased flight speed and range. The best wings to use are the 翅膀, the 日耀之翼 and the 懸浮板 for their increased vertical and horizontal movement speed, respectively.
- 黑腰帶 or 忍者大師裝備 give you a chance to dodge an attack. This is especially useful in combination with Turtle armor and 十字項鍊.
- 毀滅者徽章 和 石巨人之眼 增加了暴擊率。
- Optionally a 深度計 or it's upgrades, so you can see when you move past the 0 depth line, causing the Dungeon Guardian to spawn.
- With Minions you can use 矮人項鍊, 死靈捲軸, and a 甲蟲莎草紙.
- If you use a skybridge, a 鈷護盾, 黑曜石護盾, 聖騎士護盾 or 十字章護盾 will prevent enemies from knocking you into the Dungeon Guardian.
- The 宇宙車鑰匙 can be used to outrun the Dungeon Guardian as its speed is the same as the guardian's.
- There is also a glitch you can perform with the 粘鞍 that allows you to constantly bounce on the dungeon guardian but not take damage even if you're being pushed up in to a wall.
- The 混沌傳送杖 is also quite useful as if the Dungeon Guardian gets too close, you can teleport to a safer distance.
- 還可以使用彈藥儲備藥水，能在 7 分鐘內降低各類彈藥的消耗幾率，與彈藥箱效果疊加可大大節約彈藥，增加累計輸出傷害能力。

After making the setup, lure a Dungeon Guardian between the Teleporters, and step on the pressure plate. You will rapidly teleport back and forth, and the Dungeon Guardian will stay between the Teleporters. Keep hitting the Dungeon Guardian until it is dead. Also, if you use a 悠悠球, it will stay out, even if it has a limited flight time.
Alternatively, if you decide to kill the Dungeon Guardian after the Moon Lord, you can use a Portal Gun in a similar fashion. Just make sure the portals are far enough away from each other and that you don't jump into the portal from a high distance, as you will keep the momentum when you get out at the other portal. This could make it so that you don't teleport back and forth fast enough since it takes longer to drop back into the portal once you jump out.
This method is great if you don't especially like terrain preparation, for the only thing you will need to do to the terrain is build a stairway of asphalt leading out of the 地牢 or if you have the 閃電靴 they can be used on a dirt stairway.
First summon all of your Pygmies then go into the dungeon just far enough to summon the guardian. Once the guardian has spawned go up your stairway and onto a flat area. Then begin to shoot the Guardian with your shotbow. It should completely freeze in place. Continue shooting it with your heart arrows and your Pygmies will throw spears. Also if you have anyone who could join your world to help with the fight they could use a magic, ranged, or fairly large melee weapon(keep your distance!) to make the fight go much faster. (Only works in the mobile version).
If you have killed the three Mechanical Bosses in 專家 mode, you will have access to the 機械貨車. It can travel fast enough to easily outspeed the Dungeon Guardian but reducing the speed is possible to allow it to keep up, as letting it fall too far behind will make it despawn.
Therefore, you can make a long, flat minecart track to traverse across with a Mechanical Cart to combat the Dungeon Guardian at a distance. However, Something special must be done at either end of the track, or else you will simply run into him and die upon turning around. Both ends of the rail need to have the following assembly:
This works by utilizing the fact that 傳送機s can "see" through rails. When you are riding a Minecart on a track that's directly over a Teleporter and it is activated at that moment, it can teleport you and the Minecart you're riding to another rail that's on top of another Teleporter, keeping your momentum in the process. The branching rail on top is set to a passive state (you pass through it on the bottom line without switching on to it). The bottom Teleporter has a 壓力板軌道 over the Teleporter to trigger it, but the top one does not. This is important, as otherwise you would instantly trigger the other pressure plate and teleport back into a facefull of Guardian. The top rail has a bumper at the end of the line to make you turn around to the other direction without losing speed.
Lastly, this only works if you are moving slowly enough such that the Dungeon Guardian is lured in between the two Teleporters upon teleporting. Otherwise, you'll simply run straight into him in the same manner of if you just had a bumper at the end of the rail.
This method is great to kill the Dungeon Guardian early in game, but can be done anytime. It takes awhile, so be prepared. Almost any ranged or thrown weapon can be used, but the boomerang is best, since it can be repeatedly thrown into the middle of the room. Make a large hoik loop in the main dungeon room. Make a small room with a bed on the other side of the dungeon door, and set your spawnpoint. Move below 0 depth, and when you hear the Dungeon Guardian, use a recall potion, and then use the loop. It will try to get you, but you will be moving too quickly. Just keep throwing the boomerang until it dies. This will take nearly 2 in-game days to kill the Dungeon Guardian (with a fresh character). For a more detailed explanation, see Yrimir's Dungeon Guardian on Second Night video.
- 這可能需要你擁有屬性良好的瘋狂飛斧和宇宙車鑰匙, 當然還有一對優秀的翅膀。到地牢後就垂直向下挖（一定要帶上深度計或它的升級品）。當地牢守衛生成時，趕緊利用你的翅膀逃逸現場，此時你需要儘快激活你的UFO坐騎引着地牢守衛到處跑，與此同時用「放風箏」的手法使用你的飛斧進行攻擊。建議你最好再召喚你的飛行小鬼協同你在地表之上作戰，而不是孤身一人奮戰。
Note: This strategy is no longer effective. By far the easiest method is to exploit a magic mirror's invulnerability time. Set the spawn near the dungeon, then have one player go down into the dungeon and lure the guardian out. Spam the magic mirror and the dungeon guardian will hover over the player while a second may stand near and use a fast weapon such as the clockwork assault rifle, bananarang, or bladed glove. Minions can be used to achieve the same effect in singleplayer.
- If you have 翅膀, you can dig a hole in the dungeon deep enough for the 地牢守衛 to spawn, and then fly up to the surface.
- Using Fishron Wings, and a 蛙腿 players can actually move faster than the Dungeon Guardian when ascending and descending. This means that the player can keep a fight going as long as they need, making the fight very simple.
- Two players are better than one, using these methods can make the fight easier, but still very hard, have a friend or two help you out, if one of you dies, then there's still two left, giving enough time for the player to respawn and continue the fight.
- It is possible to survive a hit from Dungeon Guardian using Beetle armor (with 3 beetle charges from beetle shell) and Lifeforce Potion (with maximum life), the damage can be reduced further with high defense and defensive potions.
- Using Minions and Tiki armor can shorten the time required to defeat the Guardian.
- Using Frost Armor with ranged or melee weapons is a good way to deal lots of damage, as the Dungeon Guardian is not immune to frostburn and will thus increase damage.
- If you're lucky enough when wearing a Black Belt or Master Ninja Gear, you may be able to dodge its attack.
- Use multiplayer. If you die, you won't have to restart again and with multiple players the Dungeon Guardian will die faster.
- If you're using a gun, Chlorophyte Bullets will home in on the guardian to maximize accuracy, whereas Crystal Bullets will maximize damage through the shards.
- Using a Phantasm is very effective if you want to use the Easy Kite Method, as it shoots 4 arrows at once. Alternatively, another effective bow is the Tsunami, which shoots 5 arrows at once, but is a little slower than the Phantasm.
- Due to being invincible to direct damage in the tutorial on console, it is possible to survive all attacks from the Dungeon Guardian. This, however, is not the best way to defeat it as one; you will be knocked around incessantly without a cobalt shield making moving a challenge and two; the absurdly high defense of the Guardian makes it nearly impossible to kill it.
- Another, unmentioned way to defeat a Dungeon Guardian is to use the Invincible Slime Statue method, requiring a slime statue and honey. You will also need at minimal a cobalt shield and the cross necklace. This requires more than one player as at least one of the players must be taking damage from the slimes generated by the statue. The other players stand outside of the "Invincibility Box" and attack the Dungeon Guardian(s) until defeated. May take 1-2 in game days to defeat.
- On the mobile version, using heart arrows and a Hallowed Repeater can stun the Dungeon Guardian completely.
- You can become invincible with the Valentine Ring and Spikes. After you lure the Dungeon Guardian out of the dungeon, you can go to a field of spikes previously set beforehand. The spike will deal 1 damage, but will be quickly replenished with the valentine ring. However, this can only happen if you are wearing Hardmode armor like the Turtle Armor.
- Using Fishron Wings , Frostspark Boots , Frost Armor ,and a Flairon can be an effective method to defeat the Dungeon Guardian as the bubbles home in while inflicting frostburn.
