Niezly pomysl z tymi tokenami
"The way it works is like this: We have two major Pandaren factions, the Elders and the Craftsmen. Completing daily quests and scenarios for each group earns you one of two currencies. The Craftsmen tokens are spent mostly on cosmetic items. The Elder tokens are spent mostly on power items. The intent here is to let players who want some optional content to be able to devote time to both Craftsmen and Elders, while more min-max focused players or players who don't want such a time commitment can stick to Elders. The Elder tokens can be used to purchase head enchants, some nice purple items, and the kind of gear you've come to expect from factions. However, they also sell an item called a Charm of Good Fortune. Imagine you can complete a quest once a week to buy one Charm for 25 Elder Tokens. You also might be able to save up a few charms, but you won't be able to hoard them until the next tier of content.
If you have one or more Charms of Good Fortune, then whenever you kill a raid boss (in Raid Finder, normal or heroic) then a new UI window will pop up asking if you want to spend your Charm on a bonus roll. If you click yes, then you'll instantly get another shot at that boss's loot table! You will always win something from the bonus roll, such as a pile of gold, gems, or flasks. However, you also have a small (but not miniscule) chance of receiving a piece of epic loot. As with the personal loot system, the item will always be something designed for your current spec. Also, just as with personal loot, the game doesn't analyze if you already have the item, if the item would be an upgrade for you, or if you prefer axes to swords or anything like that.
Most importantly, winning a bonus roll has no effect on what other players win on their bonus rolls or what the boss drops normally. If you have saved up several Charms (this will probably happen when you play but don't raid every week) then you can use one per boss, but you can't cash in multiples on a single boss kill. If you want to save up all of your Charms for the final boss because he (or she in the case of the mantid raid) drops weapons or whatever, that is your prerogative, but you'll only be able to spend one per kill. If you want to save up your Charms for heroic bosses, go for it."
