You can obtain refinement materials at the Sulan Bridge portal (5477, -1983, 9) by approaching the NPC known as Cita Ceres. You will need to purchase Peculiar Tickets and exchange them into Curious Beads as Cita will only accept Curious Beads and Ausgyth Points in exchange for the materials. Additional Curious beads can be used to offset the amount of Ausgyth points you need to spend.
You can also purchase refinement materials from the Ausgyth vendor along with other materials to help the speed up your character's progression. You are able to obtain Ausgyth Points just by leveling up, by the time you reach level 59 you should have approximately 70,000 Ausgyth Points. Alternatively you can buy a Nine Chain Chest from the cash shop to gain a random amount of Ausgyth Points.
