Challenge: Most jewels/dragons on 1 board?

I’m curious how many dragons or jewels you have had on the screen at once. Sometimes I get bored farming & see how many I can get before the board implodes :slight_smile:
I could never get more than 5 or 6 with a normal team.
Today I decided to take it up a notch. I could have just used 1 hero, but it would take forever to beat the bosses.
