How to get Tier 4 Class Catalysts?
Hey all! So just under a week ago today, I took my 4* Duped Gwenpool to Rank 5, which took all of my Tier 4 Skill Class Catalysts. Today I pulled a 4* Blade, so I was wondering what the quickest way would be to get the other 3 Skill Class Catalysts I need to take him up to Rank 5 as well. Also, I would really appreciate if you could share any tips you may have on getting a lot of ISO. Thank you!
