- 通常打 Boss 我们需要一个大而平坦的表面，使得有足够的操作空间。考虑到地牢守卫的超高攻击防御值与血量，若与它接触，则几乎百分之百能瞬间秒杀掉你，你最好的应战方式就是逃脱它。因此对于地形的准备，你有两个较好的选择。第一种方法是单纯使用整个地图的空间，通过使用重力药水快速地移动。你将会比它更快地坠落，且当你斜向移动时速度还能更快。第二个选择是修建一条非常长(单层)的天桥(天桥)。你可以设法使得自己在天桥上水平奔跑和用翅膀跳跃时和地牢守卫一样的快。为满足当你想从它的攻击下逃脱时的需要，应当修建一个斜向的“天梯”(使用除平台以外的任何物块)或建造沥青的跑动天桥。
- 也可以通过使用 冰雪块制作一个大型的快速道，使用溜冰鞋或霜花靴快速移动
- 高射速的远程武器有类如链式机枪、鳄鱼机关枪、巨兽鲨、迷你鲨、太空海豚机枪、星旋机枪和乌兹冲锋枪等。把他们与水晶子弹配合使用可以造成更多的额外伤害，使用叶绿弹和链式机枪也可以以疯狂的速度造成巨大伤害。由于在攻击时，任何武器造成的伤害都会被归结为 1 或 2 Hp 伤害所以使用攻击速度更快的武器会很有帮助。切记一定要带上足够的弹药，可以认为 2 满组的弹药是最低的携带限度，不要忘记无尽火枪袋在这种情况下是非常有用的，最好也带上。
- Bows that may be useful are the Tsunami or Pulse Bow, due to them firing multiple projectiles. Combine them with Holy Arrows or Heart Arrows for more damage (which is mainly useful if you do not make use of the skybridge method). If the player happens to undergo the Lunar Events, the Phantasm is, without a doubt, the prime bow to use because of the ability to fire a continuous stream of arrows, as well as a 66% chance not to consume ammo. Using this bow with Holy Arrows or Frostburn Arrows is a great strategy.
- The Piranha Gun is a very easy to use ranged, 'homing weapon', that deals significant damage.
- Useful magic weapons would be Razorpine, Crystal Storm, Leaf Blower, Bubble Gun and, if you use the skybridge method, Blizzard Staff.
- If you want to use melee damage based weapons using Vampire Knives, the Scourge of the Corruptor, the Mushroom Spear, Terra Blade, Solar Eruption, the Possessed Hatchet, or the Flairon are possibilities.
- 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 Stardust Cell Staff or Stardust Dragon Staff to do lots of damage while the player concentrates on dodging.
- Any bow that has higher damage than a Silver Bow or a Tungsten Bow using Heart Arrows, because Heart Arrows will stun the Dungeon Guardian, giving you time to maneuver.
- Cosmic Car Key and Seedler 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.
- 使用重力药水、幽灵靴亦或是闪亮红气球，当然也可以是这些饰品的升级版本。 These will be needed when you reach the end of the skybridge to jump over the Dungeon Guardian when switching direction. 此外，玩家需要能够使奔跑达到水平移动速度上限。
- If you do use a 重力药水Gravitation Potion, an item to negate fall damage or provide running may still be useful.
- If you use any type of wings, the Frog Leg is very useful because it provides 50% increased flight speed and range. The best wings to use are the Fishron Wings, the Solar Wings and the Hoverboard for their increased vertical and horizontal movement speed, respectively.
- Black Belt or Master Ninja Gear give you a chance to dodge an attack. This is especially useful in combination with Turtle armor and Cross Necklace.
- Destroyer Emblem and Eye of the Golem for their increased critical chance.
- A Mana Flower, in case you use magic weapons.
- Optionally a Depth Meter 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 Pygmy Necklace, Necromantic Scroll, and a Papyrus Scarab.
- If you use a skybridge, a Cobalt Shield, Obsidian Shield, Paladin's Shield or Ankh Shield will prevent enemies from knocking you into the Dungeon Guardian.
- The Cosmic Car Key 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 Slime Mount 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 Rod of Discord is also quite useful as if the Dungeon Guardian gets too close, you can teleport to a safer distance.
- 还可以使用弹药储备药水，能在 7 分钟内降低各类弹药的消耗几率，与弹药箱效果叠加可大大节约弹药，增加累计输出伤害能力。

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 Yoyo, 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 Dungeon or if you have the Lightning Boots 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).
跃入孔洞中会召唤出地牢守卫，使用快速传送回家（需要在地牢附近），从家里跑出来即可开始战斗。利用寒霜盔甲，你可以在强势的霜冻减益效果下每秒输出最高 32 点伤害值。使用心箭能定住地牢守卫而 或 会造成多支箭矢集火于地牢守卫，这样便能更快杀死它。这些你完全可以独自实现，而且会让杀死地牢守卫的用时缩短到两分钟之内，甚至一分钟不到。
If you have killed the three Mechanical Bosses in Expert mode, you will have access to the Mechanical Cart. 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 Teleporters 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 Pressure Plate Track 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.
- 这可能需要你拥有属性良好的疯狂飞斧和宇宙车钥匙, 当然还有一对优秀的翅膀。到地牢后就垂直向下挖（一定要带上深度计或它的升级品）。当地牢守卫生成时，赶紧利用你的翅膀逃逸现场，此时你需要尽快激活你的UFO坐骑引着地牢守卫到处跑，与此同时用“放风筝”的手法使用你的飞斧进行攻击。建议你最好再召唤你的飞行小鬼协同你在地表之上作战，而不是孤身一人奋战。
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 wings, you can dig a hole in the dungeon deep enough for the Dungeon Guardian to spawn, and then fly up to the surface.
- Using Fishron Wings, and a Frog Leg 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.
