Hey, this is the final boss of the extra stratum of Etrian Odyssey. The main game ends at floor 25 but the extra stratum is made of 5 new floors carefully designed to drive you crazy. If you are patient enough to clear them all, you get to fight one of the hardest rpg bosses ever. About half of his attacks are in pattern and most of them are the elemental attacks, which deal about 2000-4000 damages if you aren't prepared. So your only 2 choices is to increase your elemental defense enough to be able to withstand them or write down the pattern with trial and errors and use a protector to completly absorb them. But the later one is quite boring. So I took the first choice and got a medic(not a cleric dumb me heh) and maxed her immunize which decrease elemental damages a lot and also physical damages. Boosting it increase its effectiveness even more. I also got 4 tourmalines which require 10 tri-color and 130k gold each. They also help with the elemental resist. I'm obviously not...
