This makes no sence. Defiling Aura is telling ur opponent she is 3 spaces away. She can't go across a meat wall when stealthed, cuz when she does Defiling Aura causes ur opponent noticed about that. In this case Hidden: Dead Magic Zone is less useful. It is funny to see her base ability disturbing one of her upgrade abilities.
Awww, the dream ;_;7 Also, I do not get the problem with hidden DMZ and defiling aura. At one hand, hidden procs at the end of the players turn, so the opponent will noticed where she was at the end of your turn anyway, and at the other hand, fascinate and sonic aura are much more noticeable given than both are base abilities and one directly pulls the opponent champion closer to her, and the other is range 2. Hidden still protects against ranged champion and single target spells (until she is revealed, obviously), so is not like an entirely wasted upgrade. Stun on the jakei maiden, on the other hand...
u can move ur hidden DMZ champions from one DMZ to another without destealthed, since the hidden DMZ only checks the condition at the end of turn. In this case the opponent will not notice at all. When u have champions with shadeskrike or spell like Despoil, that happens quite a lot. Beside that I find Defiling Aura very useless, is there any good use of it at all? It is FW only ability.
