Grinder

For the grinder in Borderlands 2, see The Overlooked: Shields Up.

The Grinder in Concordia.

The Grinder is a "crafting station" device in Borderlands: The Pre-Sequel which consumes three weapons or items fed into it and produces a new, randomly selected item as a result. There is one grinder available in the base-game of Borderlands: The Pre-Sequel, found in Janey Springs' workshop in Concordia, which becomes available for use after the mission Grinders is completed. A second grinder is made available in Claptastic Voyage, which is found beside SYS_ADMIN in The Nexus.

The items fed into the grinder must conform to a recipe, which determines the type and quality of the output. A recipe defines a combination of item types and rarities taken as input and what rarity and type the resulting output may be.

Items of common and uncommon rarity listed as mission rewards, given within a mission, and/or having a predefined set of parts by any other means, cannot be ground. Examples include: Springs' Oz Kit, the Fervid Provacateur found in Concordia's Bank during the mission "Systems Jammed", and cryo weapons from the chest opened by Dr. Spara during It Ain't Rocket Surgery. Unique mission rewards are counted as standard blue items though, including ones found in chests.

The level requirement of the produced item is the average of the level requirements of the input items, rounded down. For example: inputting one level 50 item, one level 49 item, and one level 45 item will result in a level 47 item.

Moonstone-assisted grinds guarantee the optimal rarity (for example: moonstone-grinding three blue weapons will guarantee a purple weapon in return), and may also result in a Luneshine bonus. However, only certain recipes allow for Moonstone grinds.

Notes

• Input class mods may be for any class, including multiple classes per grind (for example: two Claptrap mods and one Athena mod). The only requirement is that they have the same rarity. The class mod produced will usually - but not always - be of the type usable by the current character.
• As of the 1.0.2 update, it is possible to obtain the Excalibastard from a Grinder recipe.
• Some varieties of purple cryo shields with Maliwan parts may be treated as legendary ones.
• A Compatibility Pack released on November 11th, 2014 added the ability to grind three purple items together, and added recipes for legendary grenade mods, shields, and Oz kits, as well as an extra legendary weapon recipe. The next Compatibility Pack (released on January 27, 2015) permitted players to perform Moonstone grinds with recipes using three purple items, though there was a fatal glitch at the time of release that usually resulted in the game crashing whenever three purple items were put into the Grinder.[1]The subsequent compatibility pack released alongside Claptastic Voyage removed the ability to perform Moonstone grinds on all purple item recipes excluding class mods.
• Although Concordia's Grinder is intended to only be usable after completing the mission Grinders for Janey Springs, during True Vault Hunter Mode and Ultimate Vault Hunter Mode, it is possible to use the Grinder before this mission becomes available or is accepted from her. To do so, the current character must step very close to the Grinder (almost touching it) and be looking at either side of the centre input device. The Grinder added in Claptastic Voyage is always properly operable, as there is no required mission to fix it.
  • If the Grinders mission is accepted during True or Ultimate Vault Hunter Mode, the Grinder will become unusable until the mission runs its normal course, and will be properly usable after its completion.
