The Blossoming Door 21- Step 1: eliminate the three Ethereal Serpents before they move. Their agility is at 415. You will most likely need at least 3 units over 415 agility to eliminate them. I chose Great Dragon, King She Slime and Purrcival.- Step 2: rush the other units. Claria's job is mainly to apply decelerate on Spooky Valencia and to heal the others.
