Dungeon Accessory

Type

This Epic Dungeon Accessory can be obtained from Catacombs and requires 24 Wither Crystals to craft. If you plan on spending some time inside of the Catacombs, investing in the Catacombs Expert Ring might be a good idea as it increases Catacombs dungeon experience by 10%. 

~28kk - ~90kk*

Price Range on the AH (Coins)

*For a fully decked out version

Weapon/ Bow

Type

This Legendary Dungeon Bow is quite unique as it does not require arrows and behaves like a boomerang instead (hence the name). It is regarded as the most powerful ranged weapon for the Archer class and, as far as other bows go, it doesn't have real competition. If you want to use it, you have to complete Catacombs Floor 4 first; Crafting it requires 15 Enchanted Strings, 10 Enchanted Bone Blocks, and 5 Spirit Bones. 

~33kk - ~35,5kk

Price Range on the AH (Coins)

Dungeon Accessory

Type

This Legendary Dungeon Accessory is an upgraded version of the Treasure Ring (which is quite expensive in itself - it costs ~3.5kk); Crafting 1 Treasure Artifact requires 9 Treasure Rings, hence its price. It is one of the most expensive, but also one of the most useful accessories in the game as it grants +3% extra loot to the end of dungeon chests.

Accessory

Type

This Epic Accessory gives the wielder a 3% discount on most shops. Theoretically, it is quite cheap (compared to other items on this list, that is) as it costs just 10kk Coins + a Crooked Artifact (which costs 2.5kk in total). But... to be able to buy it, players have to purchase a total of 15 items from the Dark Auction first. Because of this restriction, people often decide to pay 4-5 times the vendor price on the Auction House instead of grinding it themselves.

Weapon/ Sword

Type

This Legendary Sword was the best weapon in the game for quite some time but has lost its title in patch 0.9.1. It can be obtained from the Dark Auction - the more you pay for it there, the higher Damage Bonus it will get (this effect is capped at 50 million Coins), or simply bought on the Auction House. It is the only weapon that can have the Gilded Reforge added to it.

Nowadays, you can get a fully decked out Livid Dagger for a fraction of the price of a "good" Midas' Sword.

Price Range on the AH (Coins)

*Depending on Enchants, Essences, Reforges, etc; max damage bonus version costs at least 100kk at the Dark Auction

Weapon/ Ability-Damage

Type

Just like the Midas' Sword, the Midas Staff can be obtained from the Dark Auction or purchased on the Auction House. It has the same property, of becoming more powerful the more Coins you spend on it (on the Dark Auction only) - this effect is capped at 100kk Coins at which point it grants 16000 Bonus Damage (you can pay more, but you will not gain a higher bonus). Its on-use ability, called Molten Wave, casts a wave of molten gold in the direction you're facing, dealing 16000 - 32000 Damage.

Armor/ Legendary Chestpiece

Type

The most expensive part of one of the strongest Armor Sets in the game (and considered the best for Berserkers and Archers). The set, called Necron's Armour, is a Legendary set of armor and one of the four variants of the Wither Armour. It gives very high bonuses to Critical Damage and Strength, grants a considerable amount of bonus Effective Health, and some Intelligence. The Chest itself provides +260 health, +140 Defense, +40 Strength, +30 Crit Damage, and +10 Intelligence. 

~103kk - ~115kk

Price Range on the AH (Coins)

Armor/ Special Dungeon Helmet

Type

This extremely rare and extremely expensive piece of headwear is obtained for killing Necron THOUSAND times (or just simply purchased on the Auction House). It provides the wearer with +220 Health, +80 Defense, and +40 Strength, and has an additional effect of doubling its stats on The Catacombs Floor VII (so, it gives 440 Health, 160 Defense, and 80 Strength there).

Note: Diamond Necron Head was added to the game quite recently (17th of November 2020), so it is likely to go down in price after the market gets saturated with it.

Combat Pet

Type

Ender Dragon Pet is the most powerful Combat Pet in the game. The only problem is, its rarity matches its power; as a Rare Drop from Ender Dragons (to drop it, you need 450 Dragon Weight), in the Dragon's Nest, it is extremely hard to obtain. It comes in two rarities - Epic and Legendary and provides the highest damage increase (highest Strength, Critical Damage, and Critical Chance) of all available pets.

Accessory

Type

Hegemony Artifact is a Legendary Accessory, only available through the Dark Auction, and only while Scorpius is the current mayor. While it does not have any bonuses on its own, it doubles all Reforge stats added to it which makes it extremely powerful when Reforged. As of right now, this is the most expensive Accessory, you can get on the Auction House, in Hypixel SkyBlock (and by a large margin at that). 

~385kk - ~650kk*

Price Range on the AH (Coins)

*For a fully decked out version

Weapon/ Sword

Type

This Legendary Sword is one of four refined variants of the Necron's Blade. Hyperion provides an extremely high bonus to Intelligence (a maximum of +500) which makes it ideal for a Mage (especially if three Wither Impact Scrolls are used on it - then it becomes the best Mage weapon available), quite a high Strength bonus of +150, +30 Ferocity, and can have up to +343 Damage. It was added to the game on the 17th of November 2020, so it's still quite new and its price is likely to fall down a bit. 

~480kk - ~520kk*

Price Range on the AH (Coins)

*We've found only two on the Auction House...

Weapon/ Sword

Type

Just like Hyperion, Valkyrie is one of four refined variants of the Necron's Blade. While Hyperion is all about its Intelligence bonus, Valkyrie is geared towards Strength (+170 max) and Ferocity (60) - thanks to these stats it is considered to be the best melee weapon in the game and a top choice for Berserkers. Its price comes from its rarity, however, and its rarity comes from the fact that Hyperion outshines it in all aspects (except melee damage) after the Necron's Blade Scrolls are applied (people rarely make Valkyrie instead of Hyperion). 

END NOTE

Remember that "the most expensive" is often not unambiguous with "the best" - Hyperion and Valkyrie are the best examples. When purchasing high-end gear in Hypixel SkyBlock, always look for the highest effectiveness, not the highest price tag.
