Nazana is very underrated champ, not end-game much but early and mid-game very usefull. Her Aoe decrease atk and ally protection helps you trough waves and bosses do very little dmg to you. Get her in stun gear with as much speed, defense or hp and acc you can get and should be good to go

The problem with stun set, it s only obtainable by killing FKC and i only can clear stage 8 :/

Get Nazana and Rector Drath up to level 60 and you should be able to progress much further on dragon and mino, at least. For FK, maybe consider Oathbound, he's pretty good there and in general as well.
