At the beginning of the game you are taught how to feed the dragons and what not in the tutorial, and when you join a clan they give you some basic tips for what is best to do. This thread is for those who haven't learned all the specific strategies when it comes to how to best level your dragons. At first you dont have as many dragons so it is a little difficult to plan the best offense, defense or monster hunting march, but as you obtain more dragons you see that there is a profound affect that your dragons have on your game play. Each player has a prefered biome (grasslands, badlands, and swamps) where they get the best bonuses. When you click on your profile you can see the percentages of you biome bonuses. Once you have that figured out you can start developing your dragons to fit your wants and needs. When you go to you dragons you can see which abilities they have; what type of dragon it is and whether it gives bonuses to gathering/monster hunting or attacking/defending. You want to save all of your food for your dragons that give bonuses to attacking and defending against other players. Dragons that give bonuses to gathering and hunting monsters, will automatically level up during monster hunting. This is why it is best to save the food for your dragons that give bonuses in attack and defense. You aquire more food through hunting in specific biomes. To further explain, if you hunt monsters in a grass lands, you will aquire grasslands dragon chow and so on. You can take advantage of this. If your best biome is grasslands, that means that hopefully you are located on a grasslands node, which means its most importand to puts grasslands attacker/defender dragons as your defense. Because these types of dragons are able to best defend you, you want to feed them more. To level them up the fastest, you can hunt monsters specifically in that biome, giving you a little boost. You can use this with any type of dragon. I hope that this is helpful to some of you.
