Diamond is the rarest ore in Mount of the Gods. It is obtainable by mining boulders at a 1% rate, from opening Giftboxes, or from utilizing the Gambling Totem. They are high yielding as a blessing, but their primary usage is to create Temples, which permanently lower the amount of Blessings requires to fulfill the Gods' demands.
Because of the diamond's incredibly high rarity, it is advisable to have someone equipped with a Miner's Hat mine all boulders made available to the commune to maximize the chances of acquisition.
Diamonds are not only obtainable from Giftboxes, but they are more likely to be acquired from them than to be mined from a boulder. This makes farming the Giant Chicken a great method to obtaining diamonds.
