I'm creating a challenege for my guild, but I'm a bit confused by the "rewards" section. I'm not talking about the overall reward of one diamond. I mean the rewards section where you usually have to pay a certain amount of gold to buy something, like a piece of equipment. It's the fartheset column on the right, next to "to dos". How does that part of a challenge work exactly?

Thanks in advance!
