What team do you have? You will need a ignore def skill to pass this

Yup that 光异界龙 will do on boss stage. He have around 18k HP with ur 光异界龙 skill 15k left around 3k u can spin some combos for him to die for stage 4, if you don't have 木妹 you can replace it with 蜜月獸. For leader do you have 水游? For ally leader you will need 解放伊登 and for the other member you can just put your damage team and make sure your HP will be around 9k+ 

With 水游 and 解放伊登 you basically cant die from the 3 stage. Unless you did not even make 1 combo for you eden to heal  When at 3rd stage and if you are fighting 索爾 you will need to make flash runes in order to damage and the others 3 which is 青龍, 玄武 and 火龍 cant basically kill you with 水游 and 解放伊登's leader skill on. When at 4th stage, use  蜜月獸 and at the boss use your 异界龙 and spin few combos to finish it 

Here's the team you can put any monster at the last 2 to pump your HP to around 9k+

yalo yalo
