The Crusade of the Six Heroes Event is an event designed specifically for experts, especially Lv. 3. I can't even pass Lv. 1, and I'm Lv. 81. Then again, I am an F2P player, and my water units kind of suck. But I remembered trying to do Serin Vortex early on, and I had Lodin with Michele friend. Yes, call me an idiot for trying that when something like Lv. 13. But I still did it through my ignorance. I didn't have many great units (3* Kikuri, 4* Twins, 2* Zephu, and 2* Mimir), but I just decided to try anyways. Luck be on my side, I got her after 12 attempts. And these Vortex Arenas... not much to say about them. Just hope that your opponent doesn't have many good units of that element.
