Yes, Utima and Omrga Weapon's Light Pilalr attack is indeed a killer move. The only exception to this is that Ultima Weapon's version does 9998 damage to a character with 255 VIT, while Omega's kills outright at lv.100. Of course, since Final Fantasy VIII uses a Parallel Level system , you don't have to be at lv.100 to beat either of the Weapons (Not to mention that Oega uses Lv.5 Death, which kills an even-leveld characters with 100 Death junctioned). Omega does have Megido Flame with does 9998 damage like Ultima's Light Pillar but hits all characters. Nice. As a plus, Omega is insanely fast. As far as Ultima Weapon goes, the trick is to simply defeat Ultima so fast that he either doesn't get the chance to use Light Pillar, or takes one members out with it. . One takes a turn drawing Eden, and Squall spams Renzokuken in the hopes of invoking Lionheat. The chances of Lionheart activating are a lot higher when all the party members are nearly dead or two of them are already KO'd. If Light Pilalr hits the "wrong" person, then just revive himher ASAP with a Phoenix Down/Life (not Full-Life). Also, it really helps if your party enters the Underground Research Lab with Squall in critical status already, or then you'll have to see it it that Squall gets beaten badly enough on the way down to meet Ultima Weapon (which shouldn't be too hard since the place teems with above average enemies + battles you can't avoid like Behemoths + Bahamut and Ruby Dragons if you answer Bahamut's questions wrong).
