1. In addition to maximum number of players in party being 9, add another
limit that maximum levels of partymembers combined can be, let's say 600.
2. Amount of rebirths a leader has adds another 100 to the limit (3 rebirths
and one can lead a 9-man 100levelers)
Lets say a mighty Janne Petteri is a level 100 eternal and creates a party of
9.
While fighting against mighty bunny at diggas he dies and leadership shifts to
random player who is a mortal. Now eternal bonus isn't counted anymore so our
mighty new leaders supposedly kicks out 3 members who dies in instant to
mighty bunny. Sounds fun tho.
