Quest Information

Professor Onai's Assignment
Quest Type Main Quest (Assignment)
Requirement(s) Complete Percival Rackham's Trial
Rewards ・ Descendo
Description Professor Onai wants me to field test Depulso on a levitated enemy. She also wants me to collect Troll Bogeys, so I will need to find and defeat a troll to complete her assignment.

Unlock the Descendo Spell

Descendo is a Force Spell that you will unlock after completing this Assignment and returning to Professor Onai. It's a great air juggle combo finisher as, although it can't deal damage on its own, it can deal heavy damage on airborne enemies as it slams them to the ground.

An example chain of Spells is Levioso, Accio, Flipendo, then Descendo—each with Basic Casts in between.

Air Juggle and Descendo Finisher Combo
Levioso → 3x Basic Cast → Accio → 3x Basic Cast → Flipendo → 3x Basic Cast → Descendo
