How and where to get Tier 6 Class Catalyst and Basic Catalyst?

TraxxFin_105

Hi all, i'm Traxx and i have a question. I completed Act 6 but now there is one more requirement where i need to rank 3 atleast one 6* in order to become a Thronebreaker but the problem is I couldn't find T6 Class Catalyst and T6 Basic Catalyst anywhere. How do i rank up the 6* without these catalysts? Where to find them as they are not in the Act 6 and not in the stores as well.

You don't need T6 basic and class catalyst for rank 3. Only T5 basic and T5 Class catalyst are needed. Which are everywhere from glory/battlegrounds/rankup store to monthly event quest, side event quest, act 7, ...
