Ether Crystals are named according to their rank and source, for example Pretty Hode Crystal or Rare Wind Crystal. The first word of a crystal's name always indicates its rank:
The second word indicates its source. If the crystal was obtained by defeating an enemy, the second word will reflect that in some way, such as Ponio, Volff, Kromar, etc. For a crystal obtained by mining, the name will reflect the element of the crystal, such as Fire, Water, Wind, Earth, Ice, or Electric.
