I emblemed Chao to +19 (715hp, 749def, 1220hp) before I had any 5* archers. Seshat+1 is my tank in my raid def team(flanked by drake +7 and Onatel+1 with Zim +3 and Morgan+9 in the wings) thank to suggestions on this site. In raids against blue tanks i grap Evelyn+3,Melendor+19 and then either Hansel+18 or Lianna+3.
There are over 400 emblems in Chao. If I remove his emblems i end up with a pretty worthless 4-70 yellow and only one other 4* yellow, gretel+6.
So I feel Im damned it I do and damned if I don’t. And if I do how to split or split at all.
