@Anonymous "barb as a healer for this fight? really? to get perma freezed?"

That's the line up with just the free, basic characters. Barbara should work out fine, if you only use her Elemental Burst. That doesn't wet the party, so it should be OK.

The title for the Rewards section says Stormterror instead of Andrius

Andrius got new attack. Now he summons crystals and shoots them

Really recommended Qiqi as a healer when cryo is useless against Boreas.

I beat him just using Noelle. Mostly stood between the legs/under the belly and attacked the front legs.

If I hit his nose he went beserk and jumped back to attack. Just staying under his belly takes longer probably but far less damage to your character.
