Most basic =
- Farm mobs (KOE/exchange drops at vendor in camp)
- Do astralruns/distortions, sell grey loot
- Exchange battleground emblems for gold
- Goblinball (??? - cant tell i never play this)
Advanced =
- Reincarnations, level again (really a lot of gold) - with the gold you buy the next iridescent jar until you have 13 chars in total - they share all items from shop mounts bag and so on
- Labyrinth (people ask for players in worldchat) - you can sell the embrium for gold on your personal allod
High end =
- Build personal allod with 1 char +12 reincarnations and build all horns of plenty there - this is somehow like mining bitcoin and gives you a really nice passive income
Other:
- Do auctions - literally EVERYTHING can go well - sold a few old pieces of gear and some herbs recently for a really good price - my best auctions were items i bought for like around 5000 BC and sold them for 18.000-20.000 the day after to buyers which werent paying attention to the market at all
The fewer fellow sellers you have the more you can dictate the price
if you are the only one offering it you can top up a salty premium for exclusivity... and so on
there are some more ways to make gold, this is just what i do
