It appears you may want to rethink the design of the Cerberus/baal free for all.
Players of high power levels are sitting in the cerberus/baal fighting area and attacking/praying on lower level players that have come in to fight the monster.
In this way they are preventing them from gaining the stakes and assisting in killing the monster.
Another problem is that some members could feasibly keep attacking a much higher player to prevent him from taking the highest % of monster life, and reaping the rewards of it.
This is one of those items that doesn't seem like it should be allowed, much like the fixed Hero Realm fix. (thank you)
