Where do you get El Patron's sword!?!?!

[Michael The Soloer]

ok this is a thought just saying, but maybe its the sea charm you have. I have asked many people throughout the game who have all the good stuff, i just have general's broadswor di got from neban :P, anyway he said he had golden sea charm with a boost of 3 treasure sense, and i recently did the extra bonus thing to get bandit sea globe from raven's cove the fish guy task. So maybe it has something to do with that, ever since i got a higher sea charm, i have been getting better and better weapons, if you get a famed won, i'm thinking that you have a better chance of finding something awesome
