See Enchantment for information on enchanting Dragons, as well as requirements
Enchantment Materials are resources introduced in Update 2.3 as part of the Enchantment feature and they are used to enchant Dragons in order to increase their Base Attack and Base Health stats. They have five grades of quality and their shape and color vary according to the material's quality and the Element they represent. Lower-quality materials can be fused together in order to obtain higher-quality materials. Enchantment Materials are mainly obtained from Enchantment Chests, but there is also the possibility of trading for them in the Whale-Mart.
