Guide:The Destroyer strategies

The Destroyer is one of the bosses unlocked when the game enters Hardmode. It is extremely strong, dealing very high damage to the player even when the player has very high-tier armor. It is generally recommended as the first boss to fight following the Wall of Flesh.

Terrain Preparation
The type of preparation you'll be making depends on your approach. If you are using melee, The Destroyer is best fought on an arena consisting of tall walls with multiple layers of Wood Platforms. This will allow players to move around the arena freely, and to keep a good watch on where the boss is. If you are using ranged, pick a wide, open, flat area, with plenty of clear space for flying and dodging. The Destroyer can clear a lot of vertical space. Like any other burrowing enemy, it can only control its movements in tiles/blocks.

Another method of defeating The Destroyer utilizes a Nimbus Rod, ropes, and Platforms. Build a platform up high enough so that the Destroyer can just barely reach the player, but not so high as to despawn the Destroyer when standing atop it, and make a rope up. Place Nimbus Clouds, and then use the mechanical worm. The clouds will damage the destroyer while you fight off the probes. You may need to replace the clouds mid-fight. If you wish to do additional damage fire down at him with a Poison Staff, preferably at an angle as to do damage to multiple segments per shot.

It may be useful to summon and kill Eye of Cthulhu (he will die in a matter of seconds when engaged with hardmode weapons) before summoning the destroyer in order to spawn an extra one-use pool of Hearts. You can also choose to add a few Heart Statues wired to a Timer to supply you with some additional health. Another great help is building a few small pools of Honey and building Campfires and Heart Lanterns around the arena. Last of all you can move the Nurse in a nearby house (not too close!) or your spawn point, as the destroyer will never despawn if you use your Magic Mirror allowing you to momentarily escape the fight to heal.

A tricky alternative way of building an arena is by creating a small box, wire up a few Heart Statues around it and some honey inside it. Combine this with high defense, a Cross Necklace and a Charm of Myths. The Destroyer himself will only deal relatively low damage, less than your healing potential, making the fight very easy. Another way is to build a horizontal platform very high in the sky (200 to 300 blocks), with 1 block replaced by a Wood Platform. The Destroyer will be unable to reach you, allowing you to easily kill him with ranged weapons. Although those two ways may make the fight a lot easier, they might also make the fight somewhat boring.

Armor
This boss is actually quite easy, considering he has the most health. The mininum for armor would be a full set of Molten Armor. At this point you should have a full set. If you don't, Obsidian Skin Potions can be used to mine loads of Hellstone. But always remember that it's always good to fight bosses [The Destroyer,etc.] with friends/other players. Titanium armor is also incredibly effective against the destroyer, because of the invincibility after hitting an enemy. However, the player will need to take a lot more time gathering resources to make a full set of titanium armor. A last great option is Orichalcum armor, because of its set bonus. Flower petals frequently multi-hit The Destroyer upon flying across the screen, and can sometimes (if angled correctly) hit most of its segments length wise.

Weapons
Different weapons can have different usefulness against this boss. However due to his high health and multiple segments piercing weapons are recommended. Aside from choosing the right weapon it may be worth your time to earn some money and get a good modifier for your weapon as well.

Melee
The Destroyer is the easiest of the 3 mechanical bosses for a melee character, considering his movement in the air is limited.
 * The weakest form of the destroyer is when he attacks vertically, if he does so, it is best to use an effective sword and swing at it multiple times. This takes out a lot of it's health and if he keeps attacking you vertically, it will take a short amount of time to defeat it.
 * Right from the start, Night's Edge can be very useful, seeing that if you spent enough time farming the materials, (which you should have done by now) the damage count, with the right Modifiers can make the boss fight last about 2 and a half minutes.
 * Spears have great potential, especially the North Pole based on its high damage. If just coming out of Hardmode, after you have already defeated a Hardmode boss, Gungnir is very effective. Players are advised to shoot it upwards to achieve maximum damage.
 * The Dao of Pow can do significant damage across multiple body parts.
 * An Ice or Death Sickle would also be able to deal significant damage, while allowing you to maintain some distance from The Destroyer.
 * A large sword would be reasonably effective, or used as a backup for defeating the Probes. Good choices include; Phasesaber, Titanium Sword, Cutlass and if you have already defeated a Hardmode boss, Excalibur.
 * If you are a hardmode starter on iOS, consider using a Mythril Halberd or if possible, an Adamantite Glaive with a godly reforge.
 * The Horseman's Blade is very effective and may kill The Destroyer in a matter of moments. However, it can only be obtained post-Plantera or during the Halloween event.
 * After defeating another Mechanical Boss, the Mushroom Spear sold from the Truffle NPC will obliterate him.

Magic
For magic users, the destroyer can be defeated with ease depending on the weapons used.


 * If you happen to obtain a Queen Spider Staff, this would be a major advantage, being able to summon the Queen Spider once and then switching to another weapon, while the Queen Spider supports you with additional damage and the killing of Probes. Additionally the Nimbus Rod can be used the same way, and should not be underestimated, as its piercing ability makes it an invaluable weapon for this fight, especially for a magic character.
 * If you have obtained the Wasp Gun, this is a good choice for the destroyer.
 * Various other piercing magic weapons could obliterate this boss in no time. Most notably the Rainbow Gun, the Poison Staff, the Golden Shower, the shadowbeam staff and the Heat Ray due to their piercing ability. However if you are unable to obtain any of those you can settle for a Diamond Staff, Frost Staff or a godly Magic Dagger as well.

Ranged
As with most bosses, ranged weapons would be easier to use than melee weapons. And even while this is one of the easier bosses for melee, a ranged weapon with enough piercing can simply hit so many parts at once that it outdamages melee weapons by a great amount.


 * An Adamantite Repeater or Titanium Repeater, combined with Jester's/Holy Arrows or Unholy/Hellfire Arrows would deal quite reasonable damage. Any of these arrows would be good choices, and if Jester's arrows are too difficult to obtain, Unholy arrows do very well in this fight and are the easiest of these arrows to procure.
 * Uzi will work. Combined with Meteor Shot or Crystal Bullets this can do nicely.
 * If you already defeated one of the other mechanical bosses you may consider using a Megashark, Flamethrower or Magical Harp, the latter of which is the perfect weapon against the destroyer, due to its infinite piercing ability and lingering projectiles.
 * Another interesting weapon is the Cannon, which should be placed instead. It can deal high damage and pierce through multiple parts, giving great damage potential, however, it may be hard to get in a good shot, aside from aiming up and simply waiting for The Destroyer to charge through you.
 * The Gatligator with Exploding Bullets is fairly good against the destroyer, as the large amount of segments is very easy to hit even with the Gatligator's inaccuracy and the Exploding Bullets can cause splash damage possibly hitting multiple segments.
 * If you were using a Skybridge made with platforms as an arena, using the Nimbus Rod will enable you to eliminate The Destroyer very quickly, just place the clouds over the platforms near you. when he passes by, he'll receive ridiculously high damages in just one leap. However, note that the platforms must be at least 200-300 blocks high.
 * A good ammo against all the bosses especially the destroyer is Exploding Bullets (though Crystal Bullets also perform admirably), as they will deal damage from the bullet and the explosion so they deal double. also sometimes you will hit on the connection of two segments and deal triple damage due to the explosion hitting both segments. this combined with the Clockwork Assault Rifle can deal a good amount of damage.
 * Another method is to use a star cannon with at least the deadly modifier and begin shooting the destroyer. It's going to most likely kill it due to the star cannon's high damage and piercing ability.

Accessories
There are many great accessories available at this point. Especially (Frozen/Leaf) Wings would be of great help, as well as Lightning Boots. Harpy Wings are also a good choice. Those two accessories would allow you to move almost freely through the air and on the ground, making it a lot easier to evade The Destroyer and his lasers. A must have for melee users, as well as being useful for ranged users, would be the Obsidian Shield, preventing you from being knocked around by the lasers, both from The Destroyer and the Probes. The Mana Flower is less useful during this fight, as the Probes you kill will almost always supply you with enough mana and drinking a mana potion once during the fight isn't a great deal either. Even though this boss is immune to all debuffs, the probes that it releases are not, so items like the Magma Stone or other items that inflict debuffs are useful.

For the remaining accessories the Cross Necklace (or Star Veil) are extremely useful due to their ability to lengthen the time delay until you take more damage. The Charm of Myths will also help you survive longer because of its regeneration and potion sickness decreasing effect. If you rather go for more damage an Emblem (or Mechanical Glove/Celestial Emblem for melee/magic users respectively) would supply you with additional damage. If you do go for a mechanical glove, using a Magma Stone (dropped from Hellbats) will help in dispatching probes, as well as making it useful thoughout Hardmode, as fire damage from all melee weapons and light from pickaxes and drills is a great asset. As with all boss fights it is best to reforge your accessories with damage, critical strike chance or defense increasing modifiers.

Potions

 * As with all boss fights a good supply of Healing Potions or even Greater Healing Potions would help you survive longer and a supply of Mana Potions in case you are going to use magic weapons.
 * One of the most useful potions would be the Ironskin Potion, helping you survive longer. Regeneration Potions also help for this.
 * A Bowl of Soup, Pumpkin Pie or Cooked Marshmallow can never hurt and are quite easy to make.
 * A Hunter Potion could be useful, so you can see where The Destroyer is going to surface and a Swiftness Potion to evade him.
 * In case you are going to use a repeater the Archery Potion is a must have and since they last four minutes you should make 2-3 of them.
 * If you prefer magic weapons instead a Magic Power Potion, Mana Regeneration Potion should be used instead. Also the buff from the Crystal Ball would give you some advantage.
 * If you are going to use melee the Thorns Potion could come in handy, but avoid using flasks, because The Destroyer is immune to all debuffs.
 * Shine Potions and Night Owl Potions are helpful, but not really essential. They just make sighting other mobs and the terrain easier.
 * Featherfall Potions and Gravitation Potions are also useful if you want more control while in the air or have limited access to the flight accessories.

The Fight
The Destroyer is almost exactly the same as the fight with the Eater of Worlds, in that it digs around and launches up at you every chance it gets. Just sidestep the body and keep wailing away at it. Occasionally it will launch a few volleys of Death Lasers at everyone fighting him. These hit for about 15-20's on players with 40-50 defense. The Destroyer also spawns Probes throughout the fight. It spawns them very often at first, and then the spawn rate slows down a good bit as you kill them off. Probes drop a 20HP Heart when killed at a 33% drop rate, so for the most part health isn't too much of an issue with this fight.

The Probes are both a blessing and a curse. A curse as they get in your way and can attack you for decent damage with their lasers (a bit more if you collide with them). They are a blessing in disguise, however, as they can be a source of health by killing them when you have less than full health: They can drop Hearts for later healing. Careful management of Health Potion usage and Heart collecting will keep you nice and stocked on health. Just drop to the ground when it's relatively clear and gather some. The Hunter Potion will let you see The Destroyer in the ground, so you'll know if you have to evade instead or can keep going for the hearts.

If you're fighting on a wide, flat plain, it might pay to occasionally just run across it until The Destroyer appears. Doing so might cause it to spread a large portion of its body along the ground, making it an easy target from above. If you have the horizontal space (and speed), make use of it by flying a decent distance back and forth instead of only staying in a particular (horizontal) area to help spread its body out. The more of the body you can keep exposed (and accessible to attacks), the more opportunities you have to deal damage.

On the other hand, if you want to hit the ground (say, to gather Hearts), you can fly straight up and hover a while until The Destroyer jumps straight up at you. You can then drop to the ground quick to gather what you need/want while the The Destroyer recovers from its attack attempt. It takes a while for it to loop back around from a high jump. Remember, outside of solid blocks/tiles, burrowing enemies have little control of their movement. This gives you the time to take a breather or collect some pick-ups on the ground.

Like most other bosses, if everyone is killed The Destroyer leaves. The Destroyer will also leave if you cannot kill it before sunrise. After a few minutes of bashing away at its health, the machine will ball. Loot from the Destroyer will be dropped from the segment nearest to a player.

For people new to hardmode, and fighting him for the first time, it is important to realize that the probes spawn as you do damage to the Destroyer. So while it may seem like a good idea to to front-load a large amount of damage (a Nimbus Rod over the spot where he first spawns, for example), you will probably find yourself overwhelmed by the sheer amount of probes spawning at once. Find a balance between damaging the boss and dealing with the probes to survive the fight.
