Atlantica

Sora and the gang are under the sea, apparently able to breathe underwater. Ariel swims by and seems a bit curious. After getting the Key of Beginnings Card, set out for the first glowing crown room on the map.

It seems that Ariel has stolen the trident from the King, throwing the kingdom in turmoil. Ariel may be doing it for selfless reasons, however Sora and the gang have to intervene and save her or else things may get a lot more complicated. Head out to find Ariel and the trident immediately by continuing to the next glowing room on the map.

Next, head on to the second crown door on the map and get ready for one last scene involving Ariel and Ursula the sea witch. Apparently Ursula has tricked Ariel into giving King Triton’s Trident in exchange for something very dear to Ariel. Run towards the last crown room on the map, use the Key to Truth, and get ready for a rather “gigantic” boss battle.

Boss Battle: Ursula

While she may be a big woman, she is not very difficult to defeat. There is no special trick to this battle other than determination and a good arsenal of Cards. To harm Ursula, you must first take out her tentacles that guard her main body. There are six of them, and they act as a shield before you can inflict any damage on the Sea Witch. After you have depleted the HP of the tentacles, they will lower briefly, giving you a chance to give it all you’ve got with any Attack, Magic, or Summon Cards in your deck. Ursula’s moves are as follows:

• Ursula uses a normal Thunder attack that is quite simple to break.
• Ursula shoots bubbles out of her mouth that, if they come in contact with Sora, will cast Confuse and cause a considerable amount of damage. Roll out of the way just before it comes in contact with you.
• Ursula shoots a very large beam of lightning out of her mouth and across the arena. This attack is easily broken, which is the best way to avoid this attack. However, if you do not have the Cards to break the attack, wait for her to charge the blast and run to one corner of the room so that you have plenty of room to roll away from the lightning. Then, as soon as she lets out the blast, continue rolling in the other direction to get away from it.

After Ursula has been destroyed, Sora is granted the Ursula Card and a free ticket back to Castle Oblivion.

Well, well, well. Look who it is. Riku appears to Sora upon entering the castle. Again Sora and Riku begin to argue, ending with a surprisingly bold quote by Sora, explaining that he intends to make Riku’s memories return to him.

Boss Battle: Riku (Part Two)

Maybe Sora was indeed a fool to pick this fight. When you begin this fight, it may surprise you at how constant your beating will become. Right out of the gate, Riku is savage while spinning, slicing, and slashing at you repeatedly. While this may be intimidating, the good news is that this makes him weaker in a big way.

Once you see Riku getting ready to use Dark Firaga, jump (don’t roll) in the opposite direction. By this point Sora has the added High Jump ability, which helps you cover much more distance than the Dodge Roll.

After the fight you get a new Sleight: Magnet Spiral.
