The Crystal Dragon is a building which passively produces Crystals which can be claimed by the player. It produces at a rate of 1 crystal for every 8 hours (3 Crystals per day, 21 Crystals per week), up to a maximum of 4 Crystals stored before collecting.

The cost is 15 Solid Rock, 20 Symbol of Transcendence, 10 Pure Magic Crystals, and 10 Essence of Magic (High). It can be built from the Craft Building (requires level 19+) that was added during the Homunculus update in September 2016.
