The first way the player can earn Raw Aetherium Crystals is by reaching 'Milestone Rounds.'

From the end of round 10 and the beginning of round 11, every five rounds afterward will be considered a Milestone Round. With each Milestone Round achieved, the player will earn crystals.

This would be rounds 11, 16, 21, 26, 31, etc. and it will continue to go on forever.

As the rounds get higher and higher, the quantity of crystals increases. So you will earn more crystals on round 50 as apposed to round 10.

Exfiltration
