Evos are used to ascend your Heroes. One Ascension requires few different Evos and varying amounts of each. Single colored Evos can be found in almost every dungeon and almost always appear, whereas double colored Celestial Evos (called Celestial class materials) only appear in select dungeons and have a very low chance of appearing.
The Arcane Evo is needed 79 times to fully ascend all 22 Heroes currently in the game that use this Evo.
You can buy this Evo for 800 gems. On the Ascension tab of the Hero's profile you can tap the Evo to see in which dungeon it is available and to buy it for gems.
