Crystals in cart

Crystals as shown in a mining cart


Crystals are a minor currency in Idle Online Universe. It is obtained through Mining, after clearing a field (depleting the health of 16 tiles).

Crystals may be sold for 100,000 Gold, having the highest value of all the sellable currencies.

It was hinted that Crystals will be also used in Guild Upgrades, a feature to be developed.
