Bronze trophy27.2% of playersRareBase game

Commander Zhalk is the devil fighting a mind flayer at the helm of the nautiloid, the last room of the prologue. You can ignore him and take the helm, which ends the prologue, so fight him first. He ignores you while the mind flayer is alive.

On the way, free the intellect devourer called Us and Shadowheart, the cleric in a pod, so you have four in your party.
Prepare the Command spell on Shadowheart.
At the helm, cast Command: Drop on Zhalk. He drops his sword, the Everburn Blade, and Lae'zel can pick it up and use it against him.
Push the purple bulbs lying around the helm next to Zhalk, move away, and burst one with a ranged attack. They explode together.
Keep hitting Zhalk until he falls, then touch the console.

Watch out

After a few turns two cambions (lesser devils) arrive and hit hard. Kill Zhalk before they reach you. Stacking three of the large chests from the earlier rooms in the corridor outside the helm delays them.
Once Zhalk is dead the mind flayer turns on you. Head for the console.
Touching the console ends the prologue at once.
