Astraeus is rich in Astraen crystals – concentrated in deep, dense deposits. In each Astraeus Defense match, players have the opportunity to mine a finite amount of Unrefined Astraen Crystals (UAC), while your opponent does the same.
Unfortunately, the crystals mined during the game are still at risk. In the event of a defeat, the victor seizes a significant portion of the loser's haul, adding a thrilling element of competitive risk to the mining process.
