Training × blending × combat. Explore the field and raise the strongest dragon! "DRAGON x DRAGON" is an RPG that captures with three elements: training, blending, and combat. In order to defeat the dark dragon "Genesis" that plunged the world into chaos, the boy "Willow", a descendant of the dragon messenger, grows up with his partner dragon "Kermes". Choose your favorite field from among the many exploration destinations and set off on an adventure. The items that can be acquired depending on the field and the attributes of the wild dragon you live in are different, so let's go deep into the field while consulting with the remaining physical strength of "Kermes" and the items you have on hand. The young "Kermes" returns to "1" every time you return from the search destination, but you can strengthen your basic ability by mixing the items you got in the middle of the search and giving them to "Kermes". The effect varies depending on the material to be blended. Try a wide variety of combinations and raise them to be the strongest dragon.
