I was in the CotSF, and I knew from past experience to throw an elixir to it. It says "Bingo!" and throws an elixir back, but I don't know what to do from there. --- http://www.qwantz.com/comics/comic2-1169.png
After that you can throw an item to another one of it's eyes, and again if you get the right one, he'll give you something back and if not, he'll blow you up. There's not really much way to end the battle besides him exploding or you running away. YOu could perform Zanmato to kill him, but you get no reward for it.
Whether Doom itself kills the Eye is unknown because it could actually kill the eye when it does "Death" but because it seems to always trigger the "Wrong" command we cannot confirm whether the eye is actually alive or KO'ed
Remeber Magic Urn has 5 Targets so you would probably need to kill all 5 Eyes to actually defeat it without Zanmato --- FFX UCG (BASIC): 985KB so far FFX UCG (PRO): 3,249KB so far
Has anyone actually successfully chosen the correct eye 7 straight times in onebattle? You cannot. Magic Urn always has 4 correct eyes and 1 wrong eye. After you get correct eye it turns into wrong eye. So you can only get 4 items when fighting Magic Urn. It can give you 7 different items. There are 5 different patterns to eyes. --- CenetaurmanE52-DRINKING IS BAD! DON'T DO IT, OR YOUR SOUL WILL BETAINTED BY EVIL PUPPIES, GRAPE SODA, AND CHINESE WHORES!
