Once you get through a big chunk ofYs X: Nordic’sstory, you’ll start noticing a small pattern in its boss fights. You’ll essentially get two fights with each of the three main Griegr villains, with the first fights ending up in the villain somehow escaping. The first villain this happened with was Jord in her fortress.
After escaping from the fort and the fight against Grimson Balta, she’ll finally challenge you again as you’re about to escape the Griegr warship. However, this time her form will be quite different and her attacks a lot more deadly than before.

Thelx Sirene will be the first boss with health in six digits, and the worst part is that you’llface her right after defeating the Naglfar Nucleus, which will likely leave you with a shortage of resources. Her high defense also makes it quite difficult to breach through her durability and deal damage to her.
Here’s what kind of attacks you may expect from this boss:
Description
Slash Attacks
During the start of the battle, you’ll commonly see Thelx using one to three slash attacks where shereadies her swords for a short momentbefore using them on your active character.
These attacks can be easy to predict, making them a great source for revenge gauge building.
Red Attack
Thelx’s red attack is one of the easiest to dodge sinceit’s a simple stompthat happens right after her red charge ends. If timed perfectly, this parry can lead to a special animation to deal a lot of damage.
Spawn
After losing a certain amount of health, Thelx will spawn a bunch of small enemies on the field before diving into the water. She willthen arise from the back of the shipand deal three instances of attacks once she reaches the ground.
This attack is nearly impossible to dodge, so it’s recommended to try and parry it.
Dive Attack
After the spawn attack, Thelx will regularly dive into the water and emerge from the other side toperform a similar attack. However, this one will be easier to just sidestep.
Orb Attack
Thelx will sometimes spawn purple portals all across the battlefield with orbs coming out of them. These orbs will home in on your character, and the best way to avoid damage is by parrying them.
How To Defeat Thelx Sirene
Even after boasting a high HP and DEF with consistent attacks. Thelx Sirene is thankfully not going to be as much of a challenge as Naglfar Nucleus. The main focus here should be on dodging or parrying its attacks since most of them can be easily avoided. The buildup of revenge gauge can help you defeat her easily.
You can also attempt to use some AoE abilities toget rid of her minions as quickly as possible. Thelx can apply a bit of Paralysis on your characters once she enters the second phase at 70 percent HP, so you can also have some solid medicine to deal with that.
