pure based on luck i guess...its helps having more ppl on the room and getting more stars though...

solo is a pretty bad idea for farming rare mats...the rates are kind low...

but be sure to try to kill all parts of the boss (some bosses only drop rare mats if a certain part is killed, i dont think claudalus is one of thoses though...)
