Named quest rewards

Although most quest-givers allow you to select one item from a randomly-generated list of treasure items, certain multi-part quest chains have a fixed list of named, pregenerated items available. Almost all such items are Bind on Acquire (disallowing exchange between characters). You won't be able to choose freely between those, since all the quest-givers replace some of those items by random ones "of equal value".

Particularly useful (and popular) items in the following lists include: Black Widow Bracers, Graskitch's Skullcap, Puzzle Cap, Carniflex, Golden Cartouche, Iron Manacles, Linen Handwraps, Black Wolfskin Belt, Blademaster Gauntlets, Crimson Gemstone, Splinterskull Acolyte Ring, Mummified Bat, Jeweler's Loupe, Shrunken Head, Scavenged Warplate, Retribution, and Spectacular Optics. Almost any character will want several of those items as soon as they become available.
