I dont like buying them from john or the broker. is there raids i can do to farm them? Should i save my source marks for gear or for catalysts?
You can’t currently farm for them. Depending on your cr source marks are rather not useful unless you still need the styles from vendor 00 and 22. Other than that the only 2 things worth buying with them are either catalyst from John or quarks from the vendor next to booster gold.
