The Corrupted Empress

Then let's say you bring 1 Evan, 1 Aran, 1 Battlemage, 1 Shadower, 1 DrK, 1 Bishop and 1 Mechanic. Hooray for the other 4 lucky ones from any job that get to come with you to fight this boss

This fight requires people level 190, you should also be able to bring whoever you can count with. There is no guaranty that you will find enough characters of that level or certain job to, lets say, provide HB to all parteis in expedition, let alone keep smoke screen up for the whole run. Even then, if your strategy consisted on invincibility skills for the whole fight, the sucess of it would rely on the precision of every of your players on using these skills in time, more than"who should I take?". If an expedition was able to pull this and kill the empress would you say they cheated and don't deserve it? I don't think so (Although I doubt an only shadowers/battlemages expedition would deal enough DPS to take down these bosses in 1 hour).



What OB3LISK said.

I believe a 9/9 party system would make this beatable while still remaining a challenge. It still gives some 'free' space for other party set ups and it fits nicely in the maximum of 18. But I guess everyone is entitled to his own opinion. Not to mention that we probably don't know enough about this boss yet to properly debate this.
