I just ran the daily with a S/L and I realized I massively fucked up! This is basically a mix of Tin Parade and Coin Creep, but with a twist. If you kill all the enemies on screen in a turn, the quest ends. But if there are any surviving monsters, more will spawn in the next turn. You have 5 turns before the quest ends, so in theory if you always let at least one enemy survive, and you wipe them all in the final round, you get the most money out of it.
The first time I ran it, I was messing around and they kept spawning until they started to overwhelm and wipe my characters out, so I S/L'd and when I killed everything in the first turn the quest ended with only 1200 coins.
The enemies give about 300 coins per kill, so I think if done properly, you can get up to maybe 6000 coins from this quest? That's pretty good for a free daily!
Edit: Might as well post this here too. I saved the profile images so we can enjoy this amazing art forever! ^_^
