I'm stuck on the Master Ava battle (Episode 425). I need advice on how I can beat her. I'm level 200, I have Lady Luck +21, all 5 medals equipped are fully leveled (2 6-star and 3 5-star) plus the 6-stars have many Chip & Dales put into them. I can only knock off 3 of her HP bars before I die (I can survive 2 turns). I don't have jewels to continue and I don't have money to buy more jewels. Can I be helped or am I stuck until I get more jewels?
