Ahhh, that was super close! I lost at 387/400.
This is the attempt with Thorns and it went much better than what I had going before. The insights: Yu is perfectly fine instead of Ulpi, but he NEEDS constant healing. This time I dealt with the flyers well, but the upper lane remains a problem. They all focus Amiya, who can take some abuse if Ptilo's and Paprika's skills are up. But there are times when it's not enough. Like a fireball hitting at the same time as a ranged volley. So I think I need to squeeze in another healer... or someone who can take hits better than Amiya.
