What's the best way to grind for treasure Maps?
Back in the day I used to grind Wind and kill wisps for them and pirates just not sure if there is a better way.

I got a like 6 frayed from clearing moonglow down to the graveyard and 2 worns from trolls recently

Also net fishing. Mostly lvl 1s and 2s but do get some higher ones sometimes

Oh I have PTSD about fishing with nets. WAY too many deaths haha.
