Hi guys, i have a question, I want to know, how can I stun dark mages (in tower vigía) with a Warlord, because I saw a some ppl than can do it. I stun moobs all the time, but the only one that I can't stun are darks mages. When I say "Stun", I refer to, even I attack them, they can't attack or defend, but if I stop of attack them, they wake up and attack me. What stats I need to up? Maybe I need more HASTE? Or maybe more CRITICAL ? Ty For ur reply !
