Professor Onai wants you to do some homework before learning Descendo

You’ll receive this assignment after completing the Main Quest Percival Rackham’s Trial. Professor Onai will ask you to do the following:

  • Collect Troll Bogeys
  • Cast "Depulso" iconDepulso on a levitated enemy

How to Get Troll Bogeys in Hogwarts Legacy

You’ll have two ways of getting your hands on some Troll Bogeys and that’s by visiting a Troll Lair which are often found near cliff sides and mountains. You’ll have an increased chance of coming across Trolls in the "Feldcroft" iconFeldcroft region. Alternatively, Troll Bogeys can be purchased at the "J. Pippin's Potions" iconJ. Pippin’s Potions Store in "Hogsmeade" iconHogsmeade for 100 Gold.

How to Cast Depulso on a Levitated Enemy

Once you’ve completed Professor Sharp’s Assignment 1, then you would’ve unlocked the spell Depulso which Repels enemies with considerable force. However, for this assignment you’ll need to cast Depulso on a levitated enemy which can be done by first casting "Levioso" iconLevioso on an enemy, such as the "Ashwinder Soldier" iconAshwinder Soldier, then immediately following it up with Depulso.
