As you do quests, battles and events, you will earn the different materials you need for a unit to evolve. Save these materials for when your unit reaches the max level and can evolve. There are six different elements:

Fire Water Earth Thunder Light Dark

The elemental materials can be found in the following areas:

Nymphs are located in mistral and level one of the Paradise of the Fairies Spirits can be found in Morgan and level two of the Paradise of the Fairies Idols are in St Lamia and level three of the Paradise of the Fairies Totems are in the corresponding Oasis of the Gods stage Mimics are in the Cave of Desire during the Tuesday events
