As you progress throughYs X: Nordics’story and realize the dangers posed by Griegrs, you’ll quickly meet some formidable enemies. One of these will be Joro and her new pet called Ioi. The latter will be a giant monster capable of easily destroying everything in its way, including people and massive walls.

This enemy will first chase you out of Carnac since you’ll not have the means of dealing with it. However, you’ll meet it again while going through Lecto Island, and you’ll have to defeat it this time if you want to progress further into the game.

Ioi Overview And Attack Pattern

Even after meeting all the bosses in Ys X: Nordics, Ioi will still feel like one of themost intimidating enemies because of its massive physique and loud roars. To complement its bulkiness, Ioi has a whopping 17,000 HP pool that you’ll have to get rid of. However, the worst part is that it regenerates its durability bar twice during the battle after the first removal.

Having 75 strength and 82 defense, this boss can easilywalk all over you unless you understand its attack pattern. This is especially true because your characters will be quite weak when you fight it:

Description

Claw Attack

You’ll see Ioi commonly bend to the ground and move its claw in an arc-shaped path. Thisattack is pretty far from its body, and you’ll automatically dodge it as long as you stay close while attacking.

Leg Stomp

With how much taller Ioi is compared to Adol and Karja, it’d be surprising if it didn’t try to stomp on them. This boss commonly lifts its legs in the air before stomping the ground, and thisserves as the best attack to build your revenge gauge.

Due to its predictable nature, you can simplypress the parry button as soon as the leg starts moving back to the groundand get high multipliers on duo skill damage.

Red Attack

You’ll likely see this attack from the boss after getting rid of its first durability bar. In it, you’ll see a red glow around the boss' body for acouple of seconds before it throws its entire body on the ground.

This attack deals a lot of damage, so you can just run away from the boss to dodgeit if you’re not confident with the parry timing.

Blue Attack

This is another commonly seen attack after the boss' first durability bar is drained, and you can easily dodge it bypressing the dash button as soon as you see the blue wavescoming at your character.

It becomes easier to dodge thisif your characters are farther awayfrom the boss.

Rush Attack

The final attack you’ll see the boss occasionally perform iswhere it runs a short distance and then either punches the airor the ground depending on your position.

During the last phase (after the boss regenerates its durability for the second time), it’llstart using all these attacks one after another.

How To Defeat Ioi

Now that you understand how to dodge every attack performed by the Ioi boss, the next step is to figure out the best way to defeat it. Since this battle is quite early in the game, it’s highlyrecommended to stock up on some health potionsand eat one of the lunch boxes that can provide you with a battle buff as soon as it starts.

These can have a huge impact during the early stages. Another thingyou’d want to consistently use is the Double Smash duo skill. If you look at this skill’s description, you’ll notice that it has a whopping three and a half bar of Break damage, which is phenomenal for breaking Ioi’s durability bar.

If the durability bar is already broken, you caninstead use the Cross Edge skillto deal higher damage.

Both these skills get a massive boost with the Revenge multiplier,which is also easy to build for this boss due to its leg stomps. Once you master these two duo skills, you’re able to easily beat this boss without losing much health.
