In its final state, Xeno'jiiva will lift itself into the air with its massive wings far more often.
This can one shot you, so should you see him begin to rear up on its hind legs, RUN. The ones to really watch out for are the beams and balls of energy he shoots out from his mouth, as these do high amounts of damage as well as an attack where he slams both front legs into the ground that will cause a delayed massive explosion. all of his attacks take fairly large amounts of damage, however he will rarely combo you. Having an Insect Glaive in your party can be a useful tool for this. Following this attempt to break its head for a possible item drop and finally if you can go for the wings. After you've cut off his tail, or if you find yourself near them, go for his front legs. It's severable and often is close to the ground in the first stage and map before he begins flying in the second zone.
He will go through stages of enragement, as well as two map layouts. Its attacks are extremely telegraphed, and his movements are slow and deliberate. Xeno'jiiva is a different breed of Elder Dragon than you've fought thus far.
