Walkthrough for Rebel Suppression, the 114th main quest in Crimson Desert. A large-scale siege battle at Thornbriar Fortress where Kliff must reduce the rebel forces to zero percent, with optional siege tower destruction and a Cursed Knight preview encounter.
Rebel Suppression is the 114th main quest in Crimson Desert and the seventh mission in the To Demeniss sub-chapter of Chapter 8: Blood Coronation. This is the chapter's large-scale siege battle. Turncoats have seized Thornbriar Fortress, and Kliff must fight through waves of rebels to bring the enemy force percentage to zero. The quest also has a preview appearance of Fortain, the Cursed Knight, who will become the next quest's main boss.
The siege uses a percentage bar on the left side of the screen that tracks remaining rebel forces. The bar starts at 100% and decreases as you kill enemies and (optionally) destroy siege towers. When it hits 0%, the quest completes immediately.
Siege Towers (Optional)
Three tall wooden siege towers are positioned around the fortress. Destroying each one reduces the enemy percentage by roughly 5%. To destroy a tower:
Find a nearby cannon. Cannons are placed on battlements near each tower.
Aim and fire. Use the cannon to shoot the tower. It takes several hits to bring one down.
Repeat for all three. Destroying all three towers removes about 15% from the enemy bar.
Destroying towers is optional. You can reach 0% purely through killing enemies, but towers speed up the process.
Fortain, the Cursed Knight appears at the first siege tower. He is a powerful shielded enemy who will disappear after taking some damage, only to reappear at other siege tower locations throughout the battle. This is a preview encounter; you cannot defeat him here. Avoid dying to him to preserve your health and progress.
Disengage. He vanishes after taking damage. Not worth fighting.
Strategy
Crowd control is king. The Tauria Curved Sword with heavy attacks excels here, mowing down groups of standard rebels efficiently.
Keep moving. Run through sections of the fortress, clearing enemies as you go. New enemies spawn in later areas, so pushing forward generates fresh kills.
Conserve healing. The Cursed Knight boss fight begins immediately after this quest with no restock opportunity. Try to end the siege with at least 100 Grilled Meat remaining.
Ignore the upper castle marker initially. You do not need to reach the upper castle to reduce the percentage. Farming kills in lower areas works just as well.
Notes
The siege has no time limit. Take as long as you need to clear enemies and preserve your health for the boss fight that follows.
If you die during the siege, you respawn at a checkpoint. Progress (percentage reduced) is preserved.
The Cursed Knight's appearances during the siege are scripted. He cannot be killed here regardless of how much damage you deal.
