I just recently started playing Realm of the Mad God.
You start off with 100 gold, what are the most useful/effective things to buy with it?
Realm of the Mad God changed the amount of gold you get when you start to 40. Before, people had abused the free starting gold by making secondary accounts to buy stuff and trade it back to their main accounts. In 2015, the cheapest item (the Soft Drink) cost 20 gold. But you can't buy it for yourself using new accounts because it is soulbound, which means that it cannot be traded to or picked up by another player.
