The Ice Titan's primary method of attack is firing ice shards at Sora. Deflecting these ice shards back at the Ice Titan by using Guard is also the key to defeating the Ice Titan. Casting Aero will make the shards grow into bigger icicles, which cannot be blocked by Aeroga or with Guard, thus rendering the strategy useless until Aero fades. Each time Sora deflects an ice shard, he is rewarded with Tech Points, and once the Ice Titan has been hit with enough ice shards, he falls to his knees for a short period, making him vulnerable to air combos and Ragnarok. However, the Ice Titan expels a flurry of ice shards when he stands back up. The Ice Titan can also be damaged with Fire spells or Strike Raid. However, Fire spells take longer to hit than the deflected ice shards, while Strike Raid deals less damage and forces Sora to stand still, making him highly vulnerable to the Ice Titan's attacks. It is also possible to jump on the Ice Titan's hand when he strikes the ground, then ride it up to his head and land a few air combos before falling back to the ground.
The Ice Titan can also attack by summoning shards of ice from the ground, the shockwaves from its feet when it moves around, conjuring snowballs to fall on top of Sora, creating an icy mist to freeze Sora in place, and performing a longer-lasting technique that also freezes Sora. Most of these moves can be avoided simply by constantly moving. The Ice Titan can also create patches of slick ice on the ground which will trip and slightly damage Sora as well, preventing him from attacking but making him temporarily unable to be hit. Sora should stay close to the corners when the Ice Titan angrily lifts his hands in the air, which only happens while the Ice Titan is on his yellow and green HP ranges. This allows Sora to dodge two of the Ice Titan's freezing techniques.
