Xenoblade Chronicles 3: Aionios’s Strongest Locations

Late in your adventure in Xenoblade Chronicles 3, the Aionios’s Strongest topic will be added to the conversations that your party can have at any rest spot. It isn’t immediately clear what this topic relates to, or where you need to go to complete it. Luckily, we’re here to help.

Broken down, Aionios is the world that Monolith Soft‘s expansive JRPG is set in and it’s likely that you will have already guessed that the “strongest” part relates to the monsters that inhabit it. This is positioned as a late or post-game challenge for you to tackle, which will eventually lead you to go toe-to-toe with the game’s mightiest enemy.

After first picking up the topic in the City (I believe it was around the street market area), there are four Unique Monsters – Kilocorn Grandeps, Perilwing Ryuho, Dreadwyrm Nizoont and Levialord Empireo – that you must hunt out and slay. These are among the most powerful creatures that you will face in the Nintendo Switch exclusive, which, once defeated, will reward you with the chance for your party to discuss the information about Aionios’s Strongest that you have gathered from toppling them at a rest spot.

This discussion will then unlock the location for a confrontation with Seraphic Ceratina, a ferocious Level 120 Unique Monster which, at least at the time of writing, is the most challenging encounter that you can find in the game. With your party capped at Level 99, you will need your strategic smarts about you to put an end to the greatest foe in Xenoblade Chronicles 3.

    1. But where in the City? I haven’t managed to find the topic, but I have the monsters defeated. I’m 4/5 right now.
