I got a buff called "Fisher's Intuition" while fishing off Cape Westwind today tryin to finsh the 1000 achievement. after i caught a HQ wahoo and had message in chat somethin large is looking for food ( somethin like that)

but it got away since my fishing stats are bad only like 307 gathering ._. so my questions are please..

1. what kind of stats do u need to hook those?
2. does it happen anywhere?
3. are there certain specifics to activate this buff or is it random from fishin long periods?
