Blizzard
Through thorough testing, we have figured out that a new limitation has been placed on stackable buffs.
For example, while
Schlachtruf der Drachentöter is active, it is no longer possible to use
Macht des Juju or Winterfall Firewater to gain their attack power bonuses. It is also not possible to use
Elixier des Mungos or
Elementarwetzsteins to receive extra critical strike bonuses.
