Just to let you guys know that the xp buff it's working for the monsters kill, i did some testing in some dung and I do gain more xp with the buff.

This buff is obtained by clicking on the pile of ash that is left after you burn the Wickerman for the quest A Time to Gain.

If you'd like to use this buff throughout the day, do not turn in A Time to Gain once you've burnt down the Wickerman, simply abandon the quest once you've clicked on the pile of ash to obtain the buff. You can then return to the Gates of Stormwind and repeat this process every time your buff expires (or your character dies).

Note: This buff does not stack with the Guild Perk Fast Track.

Players can safely complete the quest "A Time to Build Up." The ashes can be used at any time independent of the quest. If there are no Wickerman Ashes, then its due to the fact that an opposite-faction player doused the Wickerman. Simply wait for the Wickerman to be re-ignited and voilá! more ashes.
