With your squad, I'm afraid that it won't be able to deal enough damage to nuke Xie'Jing from 70% down to 60%, even with Lava. You need a lot more damaging abilities like crit buffs and Spark buffs to be able to effectively nuke Xie'Jing.

My suggestion is to make Griel the leader as she provides status immunity during the times at which Leader Skills are in effect. You also need a HoT buffer like Selena to get around the DoT debuff that Xie'Jing casts on you when she uses Demonic Atrocity.

Hope this helps!
