Seal of Broken Fate

Seal of Broken Fate is a currency used for Bonus Rolls in Legion dungeons, raids and world bosses, similar to the use of Elder Charm of Good Fortune or Warforged Seal in previous expansions. Only three may be bought weekly, but more may be acquired by other means up to a maximum of 6 seals.

Weekly quests
Players may choose the weekly quest route, choosing from either gold or Order Resources currencies to exchange for a Seal. The same currency may be used more than once, but each exchange will cost double the amount as the previous exchange in the same currency.
