Through thorough testing, we have figured out that a new limitation has been placed on stackable buffs.
For example, while
Rallying Cry of the Dragonslayer is active, it is no longer possible to use
Juju Might or Winterfall Firewater to gain their attack power bonuses. It is also not possible to use
Elixir of the Mongoose or
Elemental Sharpening Stones to receive extra critical strike bonuses.
