I haven't seen this technique anywhere, so I'll share it. Of course, it's about the boss in the magic tower (fork tower part of the game).

Enemy names vary depending what you're playing.. so that description of the Boss should be good enough... mine was called "Omniscient".

As if it isnt bad enough that you have to split your party, now you're splitting what some might be setting up as the most physically weak / magically delicious group going to the magic tower side.

Not a problem...

WALL RINGS.. lol.. seriously.. you could put 2 of these on and go poop for awhile and this guy is toast.. as he is damaged he attacks harder. If youre all Wall, he is done.

DONT cast Berserk on this guy (ive read that somewhere), ANY technique that uses a wall like spell (ultimate if you got 2 wall rings), Carbunkle and Wall spell is your alternative, in which case I recommend MightyGrd (Big Guard), or Golem (less preferred).. whatever you have available, when or if you are caught off guard w/ the Wall and get hit w/ some level 3 spells from him.

Lastly use Odin and Odin again, etc.., he deals enough damage to get this guy to some damage and eventually cast Flare on you, which goes to himself.. pending you are "Walled".

NOTE: This is an important mention, Wall rings are also great against Bahamut... and any magically inclined enemy that can cause some major trouble for you with its spells (Mega Flare anyone?).

Berserk on this guy is a BAD idea indeed. This boss killed me more times than Shinryu! Just set up reflect and watch him die!
