why am i not having any famed weapon luck?

[Cannon Leader]

Well mates, I finally got El Patron's lost sword last night. There is no method to doing it, other than what has already been posted: persistence and luck. The sequence of events for me last night was spending a little time with darkhart, then moving to Timmy, Neban, changing servers and back to darkhart and with a party of at least 10 other pirates of varying levels (mostly 30+), the sword finally showed up in a skull loot chest. I was using a level 40 pirate, but now I think I'm gonna try to do this on a new pirate and see what happens. Good luck mates.
