15 diamonds plus a stack of iron blocks. If 1 diamond is equivalent to 32 iron, 15 + 18 = 33 So total value is 33 diamonds.
Thats what people say to act like theyre getting less value, when they know theyre getting the items but it doesnt look like they are. 32 Iron = 32 Grass = 1 diamond is what is should be, and will be in this scenario.
