Equipment

Equipment refers to various weapons, armors, and accessories equipped by characters throughout the story. In a world where the threats of war and monster attacks are ever-present, good equipment are crucial for survival. They can provide significant advantage in combat by raising the user's power level or granting special properties like Magic Resistance, or even allow the user to destroy opponent's weapon if it is of inferior quality.

Equipment Grading
Various equipment of different quality had appeared throughout the story and their quality differs greatly. All equipment appeared so far are classified into 1 of the 6 grades below, but equipment quality within the same grade can also differ by a lot.

Normal Grade
Normal (一般級) grade equipment is typical weaponry forged by normal blacksmiths and widely available to the general public. These are the most commonly seen equipment in the market.

Special Grade
Special (特上級) grade equipment is usually enchanted with some type of magic. They are considerably more expensive than Normal grade equipment (could cost 50 times as much according to LN Volume 10). Widely used among adventurers.

Rare Grade
Rare (希少級) grade equipment is powerful enough to raise the level of adventurers. According to LN Volume 9, it's difficult even for A rank adventurers to have a whole set of Rare grade equipment. Most equipment created by Garm in the beginning of series are of this level. Examples include:


 * Equipment gifted to Kaval's Party.
 * Ogre series equipment obtainable from treasure chest, after defeating the level 30 floor boss in The Dungeon.
 * Sword found by Basson in The Dungeon.

Unique Grade
Unique (特質級) grade equipment is usually displayed as the advertising masterpiece in shop or passed down as family heirloom among nobles. They are the best equipment available on the market, albeit extremely hard to find. Examples include:


 * Dragon Slayer, a greatsword given to Youm by Rimuru Tempest.
 * Exo-Armor, an armor given to Youm by Rimuru Tempest.
 * Equipment owned by Pegasus Riders.
 * Crimson Lotus, a owned by Benimaru. (Before Upgrade)
 * Hercules Edge, an owned by Shion. (Before Upgrade)
 * Vortex Spear, a trident owned by Gabiru and the Lizardman tribe's heirloom. (Before Upgrade)
 * Elemental Mail, armor owned by members of the Ten Great Saints.
 * Minotaur series equipment obtainable from treasure chest, after defeating level 50 floor boss in The Dungeon.
 * Cursed Sword and Cursed Armor used by Albert.
 * Ice Blade used by Yamza.

Legend Grade
Legend (伝説級) grade equipment is the result of unique grade equipment that contains Magisteel getting exposed to highly concentrated Magicules for many years and evolving into a new metal. Equipment of this grade is so powerful that "owning one is akin to bringing a machinegun into a swordfight". As their name implies, these are legendary works that are often sealed away from public view. Kurobe is the only known blacksmith that could craft weapons of this grade late in the story. Examples include:


 * White Tiger-Blue Dragon, a Halberd owned by Carrion.
 * Moonlight, a rapier used by Hinata Sakaguchi.
 * Holy Mail, an armor used by Hinata Sakaguchi.
 * Phantom Pain, a rapier given to Hinata Sakaguchi by Rimuru Tempest.
 * Equipment used by Imperial Guardians of the Eastern Empire.
 * Unnamed Sword owned by Gazel Dwargo.
 * Unnamed War Lance and Armor owned by Vaughn.
 * Unnamed Swords forged by Kurobe given to Hakurou, Veyron and Esprit.
 * Unnamed Dual owned by Souei.

God Grade
God (神話級) grade equipment, as their name implies, are a myth to most people. Imbued with godly powers, they only lend their power to those whom they deem worthy, and will transform into whatever forms suitable for their owner. Armor of this grade, when worn, allows the wearer's flesh to take on the properties of a Spiritual Lifeform. These are equipment used by some of the most powerful characters in series. Examples include:


 * Asura, a sword owned by Milim Nava. It takes the appearance of a long curved single-edged blade. Paired with Rudra's Deva.
 * Deva, a sword owned by Rudra Nam Ul Nasca. It takes the appearance of a normal-sized, double-edged sword.

 * Divine Hercules Edge, an ōdachi owned by Shion.
 * Vortex Spear, a trident owned by Gabiru.

Notable Materials
There are some notable materials used in series to craft equipment with higher quality.

Monster Parts
Body parts and substances from monsters could be used to create high quality equipment. For example, Youm's armor is created out of Knight Spider's exoskeleton, and scales from Charybdis can be used to create armors and weapons with powerful magical properties.

Magisteel
Magisteel (魔鋼) is metal refined from Magic Ore. It is highly heat resistant, durable and excellent in conducting magic, hence very suitable for producing high quality equipment. However, it is also very expensive due to its scarcity, costing more than 20 times as much as gold of the same weight.

Mithril
Mithril (魔銀) is an alloy created by combining magisteel with silver. Weapons made of mithril are particularly effective against undead monsters. Known equipment made of mithril includes armor gifted to Jinrai by Rimuru and Minos Bardiche found in the dungeon.

Orichalcum
Orichalcum (神輝金鋼) is a gold-colored alloy created by combining magisteel with gold. It is superior to magisteel in all aspects, including thermal properties, toughness and magical properties.

Adamantite
Adamantite (生体魔鋼) A sort of bio magi-steel on the level of orichalcum that is quite literally alive and bonds to it's user.

Dragotite
Dragotite (竜気魔鋼) Adamantite that has been mutated by a True Dragon's Aura. It shares all the properties of Adamantite but is considerably stronger.

Hihiirokane
Hihiirokane (究極の金属) Formed after exposing magisteel to concentrated magicules for thousands of years (or special conditions like Rimuru's stomach), this is the material spoken of only in fairytales and myth.

Equipment made of Hihiirokane, only responds to magic power from the owner it recognizes and will block out all wavelengths, even attempts to analyze it will utterly fail. Anything made of this legendary metal can be expected to be top of the line Legend Grade goods bordering on, if not in, God-Grade.

Equipment Enhancement
In a world where magic is publicly available, there are various ways for craftsmen to enhance the equipment they made.

Enchantment
By using Engraving Magic, the craftsmen could affix magical effects to equipment. Engraved magic gear could be infused with mana, and once infused, it was possible to execute certain magic. However, there was a limit to the number of varying magics that could be enchanted. At most, only two types of different magic could be enchanted. Moreover, it was impossible to remove the engraving after enchanting.

The Eastern Empire utilized this principle to create magic stone-powered weapons that could be used by everyone, resulting in obsolescence of Gadra's Magic Corps.

Slotting
A new way of enhancing equipment invented by Kurobe and Kaijin, based on Rimuru's idea. By punching holes into equipment, Element Cores (magic marbles imbued with the power of spirits) can be inserted into these slots, granting the equipment magic properties.

Inserting Element Cores in different combinations could yield vastly different and unexpected results. For example, inserting a water spirit core next to a fire spirit one reduces power, but having a water spirit core paired with two fire spirit cores increases power by ten fold.
