Made this video to help anyone clear Special/Exhibition for that 5 or lees attempts reward. If you're lucky you can clear this on 4 attempts. Also, if you feel that your team will wipe during 2nd and 3rd Mode, just retreat so that your attempt won't be wasted and luckily your team will a more successful chance against this difficult boss.
For alternative teams to use in Mode 1 & 2, you can check out this guide: https://fansubbing.com/priconne-event...
