For low level gold grind, i suggest either copper hammer(active) or puffer fish roll(semi-idle). You need rice from swamp & level 25 woodcutting to reach the beach for puffer fish and seaweed.
To avoid further confusion on this (be warned, this is slightly SPOILERish):
You get the ability to always skip the intro after unlocking a certain intro-related ending.
This should be fixed with the next update!
