Mastery Pennants

Mastery Pennants are cosmetic rewards in Diablo III that can be worn on the character's back, accessed through Wardrobe. Only one Pennant can be equipped at a time.

There are a total of 7 Mastery Pennants, one for each class. They all have different shape, color and symbols. Wear your brutal heritage proudly.
 * A white helmet, black and red

Let all see the humility with which you serve your faith!
 * Crusader: Zakarum sigil, black and white

Single minded vengeance need not be ugly.
 * Demon Hunter: white Demon Hunters' sigil, black and dark blue

Your martial prowess shall be worshipped alongside your 1001 gods.
 * Monk: Ivgorod ornament and Uliana's iconography, yellow and orange

All who oppose you, beware.
 * Frailty Curse rune, pale flesh and green

Summoning dead souls to do your bidding does not make you a bad person.
 * Witch Doctor: A Poison spirit's visage and totemic icons, wood and purple

A stylish addition to your dashing wardrobe.
 * Wizard: white Arcane Power Orb and scrolls (Wizard class crest), gold and magenta

Each pennant is awarded if the player beats all four of their class's Set Dungeons with Mastery rating. Ascendant Pennants are awarded for the same task, but with either Normal or Mastery rating.

The pennants may be worn regardless of class (though earning them is impossible without having a character of the specific class).

Trivia

 * On the original artwork by Aaron Gaines, the Barbarian Mastery Pennant had a joke sigil of the small swimming duck.
