Twin Valkyrs Tactics step by step:
You main challenge is for DPS to be aware of the orbs around the room, and pick only the orb color they need, and for the healers to be aware of what damage ability is going to occur next.

Twin Valkyrs Tactics step 1:
Split your raid group in 2.

Twin Valkyrs Tactics step 2:
Tank Fjola and Eydis apart from each other

Twin Valkyrs Tactics step 3:
The Fjola group picks up the black orbs and avoid picking up the white orbs.
Picking up 100 orbs will greatly boost your damage.

Twin Valkyrs Tactics step 4:
The Eydis group picks up the white orbs and avoid picking up the Bloack orbs.
Picking up 100 orbs will greatly boost your damage.

Twin Valkyrs Tactics step 5:
Healers keep watching the Bosses abilities being cast (as described above) to expect what kind of healing will be needed next.

Twin Valkyrs Tactics step 6:
Keep adjusting to the abilities (it's a bit of a random fight) until they both die (they have shared health pool)
