Room for 10 people in two summoning groups of 5.
Each team will pop 3 bosses - this means each person in each team will also get the mission reward on those 3 that are spawned by the team (= extra loot!)
If someone else is already summoning at the time we go to start this - we will switch activity and do regionals instead.
If you find yourself forced to mercilessly slaughter your teammates because they become infected with some rare mutation, keep in mind that you are only doing your job -
They would do the same for you.
