If you are aiming for the regular ending in MIO: Memories in Orbit, your journey ends with Ati, Keeper of the Heart, the sister of your character and a familiar face you’ve encountered many times while exploring the Vessel. While Ati isn’t the hardest boss in the game, the fight against her is challenging due to her vast range of attacks. This MIO: Memories in Orbit Ati Boss Battle Guide details all the tips and tricks that you need to beat Ati.
Ati Boss Battle Guide – MIO: Memories in Orbit
Ati is the last boss of the standard story in MIO. If you choose the alternate ending of MIO: Memories in Orbit, you won’t fight her at all. Before the battle becomes available, you must collect all four Voices scattered across the Vessel. After obtaining the final one from the Hand, return to Shii and speak with them.
Once that’s done, you will be taken to the husk of the Spine, where you can finally confront Ati. Before starting the fight, it is a good thing that you have some modifiers unlocked. These will help you in your fight. Some modifiers can help improve survivability and damage flow, but they are only suggestions. If you have found alternatives that better suit how you play, those will work just as well. Some of these are:
- Analyzer
- Enhanced Dodge
- Foolish Ideal
- Kinetic Thrust
- Protective Overlay
- Self-Awareness
Make sure your setup supports dodging and quick reactions, since Ati is a mirror version of you.
How to Defeat Ati
Ati is fast, small, and constantly moving, which makes landing hits difficult. Unlike many bosses, she rarely stays in one place, giving you only short chances to attack. The full fight can last close to five minutes because she frequently disappears and reappears. She also has some attacks that will drain your health very quickly.
Ati’s fight has two phases. Most attacks carry over into phase two, but they are modified. Learning her patterns in phase one makes the second phase far more manageable.
In phase one, Ati focuses on movement and quick strikes. She moves across the arena and attacks from a distance. Because openings are short, staying close enough to quickly attack with Hairpin after dodging is important.
During the first phase, Ati uses a wide variety of fast and aggressive attacks, as said above. At times, she fires a single fireball across the arena, then teleports and fires again from the opposite side, so you need to stay alert and avoid each shot as it comes. She will also pull her tendrils inward before thrusting them outward, which must be dodged to avoid taking damage.
Another attack involves Ati rushing forward with two quick strikes before disappearing and dropping straight down onto you from above. You should avoid the initial rush and be ready to dodge when she falls from the air. In a similar version of this attack, she performs the first two strikes but follows them with a third attack along the ground instead of dropping from above, so continuous movement is the key to success here.
Ati can also vanish mid-air and summon several points that turn into fireballs sweeping across the arena. To stay safe, use Striders to climb the walls and stay out of their path. In addition, she may anchor herself to the ground using her tendrils and launch rapidly across the floor, requiring quick dodging from you. Finally, she sometimes sends her hair straight toward you to pull you in for a powerful hit, and you must dodge right as the hair is released to escape the grab.
Once phase two begins, Ati becomes more dangerous by adding new attacks and enhancing old ones. The following are the attacks that you will face in phase 2.
During phase 2, at certain moments, Ati electrifies the floor and repeatedly dashes from one side of the arena to the other, forcing you to stay off the ground by jumping or using the arena’s sides. She may also appear in the air and dash diagonally downward, covering a large area, so keeping your distance or jumping at the right time is important.
Ati can dash upward from below a crystal and fire multiple fireballs in your direction, which you need to dodge as they are released. In another aerial attack, she hovers above you and drops fireballs one at a time before firing several all at once, meaning constant movement is necessary to avoid getting hit. Her basic fireball attack is also upgraded in this phase, as she fires multiple fireballs before teleporting and repeating the attack from the opposite side, requiring careful dodging.
Several attacks from the first phase return, including the tendril one in which Ati pulls her tendrils inward and outward, and some more. You must again avoid the forward rushes and either dodge the downward fall from above or the final ground-based strike. The sweeping fireball attack also returns in an upgraded form, with fireballs spawning in a more random and less predictable pattern, making wall climbing with Striders the best choice to stay safe.
Additionally, Ati improves her ground attack by combining it with repeated crashes from above after disappearing, so you must avoid both the fast movement along the floor and the falling attacks that follow. The hair grab attack also returns unchanged, but it is harder to react to due to the increased pace of the fight, so dodge right as the hair comes forward.
When Ati’s health finally reaches zero, she moves to the center and begins forming a massive Spirit Bomb-esque attack. The move leaves both of you stunned. Once you regain control, you must strike her to end the fight. Defeating Ati grants you the standard ending of MIO: Memories in Orbit.
