Yesterday, myself and a friend, who was dual boxing, attempted Odin with three BSTs. We never noticed that there is a ten minute time-limit for any fight if there are less than six players in the chamber.
We got it down to 35% or so with ease, standing back and keeping the pets alive. Then it kicked us out. I read somewhere that this was possible. However even if the BSTs were to run in and start attacking with the pets, how would they survive Geirrothr? With six targets, that equals 1667 points of damage to each player.
Even with four BSTs, its still 1250 HP to each player, making life difficult for any tarus in the party. So how do people defeat it without bringing along extra bodies for the sake of getting an extra twenty minutes?
