Have you leveled fishing yet? If so i would make a character for fishing and do the daily catches.

Keep all rare fish which are on the bottom of this wiki list and park him after a few weeks in arborstone to get daily ambergris.

Then there are Jade runestones. Can recommend parking an alt at the new kaineng jumping puzzle to get one each day.

There is also a farming route but this video probably explains it better.
