The Warforged Seal, when used, gives players a second shot at a chosen boss's loot table. When a raid group defeats a boss, each player in the raid will be prompted to use one of their Warforged Seals for a chance for extra loot. Internally, when players use a Warforged Seal, the game rolls a random number for each player, and if that number is above a certain threshold, it rewards them with a random spec-specific item off the boss's loot table. If the internal roll isn't high enough, the player receives just gold.

Players can earn Warforged Seals by completing the weekly quest Warforged Seals / Warforged Seals and turning in 50 Lesser Charm of Good Fortune. The Lesser Charms themselves are awarded from almost every daily quest in Pandaria.

The Warforged Seals can only be used on tier 16 bosses as well as on the world boss Ordos, and the Celestials.
