Seraph

Seraph (sometimes referred to as ) is an item rarity released with Captain Scarlett and Her Pirate's Booty. Seraph items seem to be somewhere between and  items, with impressive stats but with some form of drawback such as horrible accuracy or low projectile speed.

How To Obtain
Seraph items can be obtained by killing Hyperius the Invincible and Master Gee the Invincible (available after killing The Leviathan and completing the main DLC story). Shade gives the quests for both bosses. They can also be purchased from the Seraph Vendors in the town of Oasis and the Badass Crater of Badassitude.

Seraph Crystals
Seraph crystals can be used to buy Seraph weapons, shields and relics. All weapons and shields cost 120 Seraph Crystals each, with relics costing 50 crystals. Crystals are dropped by Hyperius and Master Gee (although Master Gee is currently bugged and usually drops Eridium instead). With the addition of Mr. Torgue's Campaign of Carnage (DLC 2), a raid boss named Pete the Invincible can also be fought daily for seraph crystals.
