Blazing is your best option until 102-103 weather you like it or not. After that,next stem is Desert quarry from Gludio, until 105. If I were you I would do lvl 99 dual class (if you don't have it already), get 4 certifications (use fot m atk 13% and m crit rate 5%), lvl up main to 101, lvl up dual 101,certify for m atk +3%, lvl up main 103, lvl up dual 103, certify for one more +3% m atk, lvl up main 105, lvl up dual 105, certify for last +3% m atk.
