Is it possible?

Is possible to solo "Omega Weapon"?
if yes, plz give me some details =d

Short of spamming summons and running theres no way to solo him. Here however is a method the average joe can use. You'll want to unlock Hero Drinks from the panda "Fire" to do this as you'll need quite a few... Get the Seitengrat bow and an Archer, pop a hero drink, run right next to him and use flurry of arrows. If you are not RIGHT next to him your arrows my miss the target. This will take quite awhile and He will run away everytime he is hit but eventually you can back him into a corner *for me it seems to be where Ultima spawned, Omega always runs over there trying to get away from the arrows* Just keep using Hero Drink and Flurry of Arrows then running away and waiting for the hero drink cooldown. This works with 1 player though it's not much different then spamming summons.

what do you mean with spamming summons? are u talking about summoner?

No i'm referring to the summon materias such as Odin. It's not so much soloing as being cheap with some of the higher super bosses as the re is just no way to withstand the damage *or the stuns/slows/ect.* alone. My method of using Hero Drinks and hitting Omega with Flurry of Arrows is probably the easiest way to beat him as for me the Flurry does 3000 or so a arrow and shoots maybe 7-9 arrows when I use seitengrat. It's a lot of damage in a short time.
