this board doesnt seem too bad. just match a blue and a red and if you dont cascade you should kill the two lits, then just stall on the mythlit. even a green and a red wouldve probably worked since you have full hp and zeus wouldve activated.
This isn't all the mobs. The screen was still loading for first turn when I took the picture. I matched all of the red, green and blue I could and tried to line up the yellow for cascade but didn't get it. I ended up leaving 3 mobs on the bored, locked out yellow first turn and couldnt damage them enough not being 100% for Zeus Leader.
I am starting to think a Valkyrie team might be the best for me for this dungeon but you need to get over the HP cap for round 3.
