To do this, have "Steal as Well" and "Comet" (Comet2) Materia linked together, and the "Steal Glove" accessory equipped. After defeating the Diamond Weapon that is approaching Midgar, wait until the entire storyline finishes so that you may control the Highwind Ship again. When flying the ship, it is important that you not go to Midgar or you will have to do this trick on the Disc 3. Otherwise, you can wait later if you are not up stealing Ultima's items. Fly the ship where there is a circle-like waterfall behind Junon. Ultima Weapon is hovering over the waterfall. Engage in battle and use Comet2 on Ultima. You will steal a Circlet accessory which upgrades your Magic and Spirit by +30. You can only get it when Ultima is hovering in battle. While he is on ground, you can steal Reflect Ring accessories. If you are on the Highwind and encounter him when he is flying around, bump into him five times; he will fly, then stop and charge up a blue energy ball over the area he is at. Be careful that he does not stop over Midgar or you will have to finish collecting his items on the Disc 3. Note: When you encounter Ultima Weapon for the first time, you can steal a Cursed Ring accessory which increases your status but it also induces Death Sentence on yourself. It is best that you have "Added Effect" and "Destruct" Materia linked together if you plan on using it.
