How to Win the Duel in Crossed Wands Round 3

After completing 'Secrets of the Restricted Section' and 'Tomes and Tribulations', travel to the Clock Tower Courtyard Floo Flame.

Find Lucan Brattleby to initiate the final round of the Crossed Wands tournament.

Choose to bring a companion (Natsai Onai or Sebastian Sallow) to help manage enemy aggro and deal damage.

Be prepared to face four opponents. Your companion will draw some attention, but you will need to do most of the heavy lifting.

Utilize the Accio + Incendio spell combination, learned in 'Spell Combination Practice 2', to quickly deplete enemy health.

Counter red shields with Incendio, yellow shields with Levioso, and purple shields with Accio.

Instead of directly attacking enemies with red shields, play passively. Wait for them to cast spells, then counter with Protego + Stupefy. This will break their barriers and leave them vulnerable.

Use the lock-on feature to concentrate fire on specific targets.

Prioritize eliminating enemies one by one to reduce the number of opponents you face.

Continue to use Accio + Incendio whenever spell cooldowns allow, especially on undefended foes.

As the odds shift to 2 vs 2, the fight should become significantly easier.
