Having Stronghold quests which require unobtainable gold coins to complete, is very frustrating.
Because they removed all the early gold from rapports and didnt replace it somewhere else 
Maybe adventure islands would give gold sometimes? Idk in the lower tiers. Keep an eye on the compass? Someone might know for sure though
I was told there was a reason, but The fact remains that I have a quest I picked up @ 35-ish, and I can’t complete it until I hit 50. There should be more stronghold structures available to craft to complete the Stronghold intro-quests.
Royal Crystal → Gold. Easy, that’s what AGS wants you to do.
