I was at Coral gate on Elite difficulty.
I found 21 orbs an 171 crystals
6 of the orbs were from rooms
7 of the orbs were from arenas
7 of the orbs were from vaults
1 orb was from... I honestly don't know
and the Radiants were from everywhere.
How did I do?
I'm just 4* trying to become a champion.
Oh, there's one tiny detail you're forgetting. So, did you do a full T3 run?
