Three days passed in no time.
On this day, the long-absent voice of Golden Finger duly echoed...
"Upgrade completed, monthly new features are now available."
"You will receive one summoning opportunity each month, which you can use to summon a variety of dragon eggs."
"The dragon eggs, in order of rarity from low to high are: Black Iron Dragon Egg, Bronze Dragon Egg, Silver Dragon Egg, Gold Dragon Egg, Platinum Dragon Egg, Diamond Dragon Egg, Epic Dragon Egg, Legendary Dragon Egg, Mythical Dragon Egg, and Chaos Dragon Egg."
"Dragon eggs vary in rarity, and so do the items they produce. The rarer the dragon egg, the better the chances of unearthing good stuff, and the richer the rewards. Similarly, the more common the dragon egg, the poorer the quality of its loot, but there will never be an empty egg."
"At least one precious rare piece will certainly be found in an Epic Dragon Egg and above."
