The second in the A.B.R. series of guardians, this boss is encountered inside the Singing Hill, right before getting the Hymn Crystal Purger. As noted in the description and in its ability table, this monster is the sole possessor of the Red Magic Absorption passive skill, which allows it to absorb all Red Magic casted against it, rendering all offensive Song Magic useless. Due to that, all of the damage output will have to come from your vanguards, while Aurica takes a support role, using her Blue Magic songs to heal and buff the party, which is also the only way you have for raising Harmonics in this battle.
