I’m not able to prove this in any way, but I would think there should be a way to check.
If two like color heroes attack through tile, that total power can be known. Further, the troops add to the attack power of each hero in a known way. That leaves only the crit rating, I think, which could be solved for.
I am not a wizard like Revelate, but would have thought one of the old ones had this figured.
@2Spookd I occasionally check the email this forum’s notifications go to, and logging in for what rare quests I can just in case I decide I want to play again I won’t have lost too much time given those are 70-80% of the progression in game once one only really needs 4* ascension items.
