Level required to Rank 3 a 6* champ
I recently got my first tier 5 class catalyst from act 6. And I have doctor doom as my 6* rank 2 champ who I wanted to rank up. And luckily I got a mystic catalyst for him but when I checked I have 5 tier 5 basic catalyst out of which 3 are in inventory and 2 in overflow I need 4 of them in my inventory for my doom I am at level 54
