Kaer Morhen Battle Preparations – The Two Choices

Description:
During the quest *“The Battle of Kaer Morhen”* in *The Witcher 3*, Geralt makes two tactical decisions that shape how the battle against the Wild Hunt unfolds. While these don’t affect the main story or ending, they impact the defense of the keep and how the battle feels. This guide explains your real choices—nothing extra, no filler.

🧪 1. What Should Lambert Do With the Laboratory?

Lambert suggests using the old alchemy lab. You choose one of three options:

• Use the lab to make potions – Buffs the defenders’ performance during the fight.
  
• Use the lab to set traps – Places magical traps on the battlefield that slow and damage enemies.
  
• Do nothing – No bonus; Lambert expresses disappointment.

Recommendation: Potions are better for general survivability. Traps are good for controlling the battlefield.

🧱 2. Reinforce the Gate or the Wall?

Vesemir will ask which part of Kaer Morhen to fortify before the battle.

• Reinforce the Gate – Strengthens the first point of attack; slows down initial breach.
  
• Reinforce the Wall – Strengthens fallback defenses inside the keep.

Recommendation: Reinforce the wall—it holds longer and protects more vital areas during the later phases of the fight.
