Using Levia+10. I believe any magicians who can take 3 at once would do the job. Octavia must hit 8 who should be using Taunt.
☆☆☆ Campaign 50-8 (Hard 3★) ☆☆☆
Orienne doesn't have to be strong, but she needs to attack before 7 does, so that she can put curse on 7 to protect Veronia. Likewise Viola needs to attack before 11. Joseph has to be ★6 and +9, and hits all 4 Anubis with critical.
