Equipment

Various equipment of different quality had appeared throughout the story and their quality differs greatly. Good quality equipment 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
All equipment appeared in story 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
Equipment forged by normal blacksmiths and widely available to the general public. These are the most commonly seen equipment in the market.

Special Grade
Equipment enchanted with some 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
Equipment 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 Ramiris' Labyrinth
 * Sword found by Basson in Ramiris' Labyrinth

Unique Grade
These exquisite equipment are 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:


 * Youm's set of equipment given by Rimuru
 * Equipment used by Pegasus Riders
 * Guren, Benimaru's katana (before upgrade)
 * Gourikimaru, Shion's ōdachi, (before upgrade)
 * Vortex Spear, Gabiru's spear and Lizardman's heirloom
 * Minotaur series equipment obtainable from treasure chest, after defeating level 50 floor boss in Ramiris' Labyrinth
 * Albert's Curse Sword and Curse Armor

Legend Grade
When Unique grade equipment that contains Demon Steel gets exposed to highly concentrated Magicule for many years, it will evolve into Legend grade. These equipment are so powerful that "owning one is akin to bringing a machinegun into swordfights". As their name implies, these are legendary equipment 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:


 * Carrion's White-Tiger-Blue-Dragon Halberd
 * Moonlight, a rapier owned by Hinata Sakaguchi
 * Equipment used by Royal Guards of the Eastern Empire

Mythical (Gods) Grade
As their name implies, the existence of these equipment 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. These are equipment used by some of the most powerful characters in series. Examples include:


 * Tenma, a sword owned by Milim Nava. It takes the appearance of a long curved single-edged blade.
 * Night Rose, a sword owned by Luminous Valentine, named after her palace destroyed by Veldora Tempest 2000 years ago.
 * Flame Pillar, a sword used by Leon Cromwell when he was a Hero.
 * Rimuru's katana after evolution

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
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
An alloy created by combining magisteel with silver. Weapons made of mithril are particularly effective against undeads.
