I dont know why this works in OOT but not in PoK. Ive been trying to work this skill for the last 2 days. I was in PoK and its didnt move an inch. I went to OOT to farm for the Epic and was like lets try this. It Works dont know how and why it works.
Get an EB item such as fishbone earring or Singing steel gauntlets and go to OOT and jump off the boat, sink to the bottom and play your heart out all night, i did this because at lvl 48 i was 17 in brass instruments, woke up the next morning and i was around 190, the reason to be at the bottom of the ocean is, people HATE it when they get that " so and so tries to kill you but it didnt work" message , and there is nothing that will attack you at the bottom of OOT, another option is to find some kind of area here nothing will aggro you and players do not go to =) good luck
