DustDevil has been too much more powerful than he’s supposed to be. Caused by a bug.
His Orange skill says ,”Stunned foes take XX% more damage”. However, more and more of we players have found that the UNSTUNNED foes also take the huge doubled(or even 3Xed) addional damages from some certain allies，e.g. WeeWhich、SpiritWolf、Unicorge and so on.
None of WW、SW、UC’s white skill can stun the enemies. But BEFORE stunning foes with his own white, DustDevil does help them increase their white skill damage up to a horrible stage.
