@ j05h, the 300k gun is the best, after you bought a lot of attack power.
But the 90k/100k items are best to buy first, than grind attack power and after that try to reach 300k for the gun.
Will probably take another week for the new arena to come out. Tukkun mentioned somewhere that the old one will be deleted for some days before the new ones comes.
Just wait, you could better have a good one than a rushed one.
@ksmulz Progress bar is not progress boost.
Could help if people know what they are asking ;s.
@koekert, you can cheat those quests anyway like you did with the rest...
