Lights Out Achievement Guide

Acquire a Dagger: This is mandatory for stealth kills. You can purchase one from various merchants, including the blacksmith in Tachov. Ensure it is equipped.

Obtain Stealth Gear: Equip clothing with low noise and visibility stats. Avoid heavy armor. Dark, clean, and lightweight clothing is ideal. You can find starter stealth gear during the Materia Prima side quest by completing the optional objective to steal clothes from the bathhouse at the Zhelejov Wagoners’ Inn.

Level Stealth Skill: Improve your Stealth skill by sneaking near wild animals or picking locks. The "Tight Grip" perk (Strength Lv10) can be helpful, but there's no specific level requirement; just ensure you can sneak up on enemies effectively.

Find a Target: Seek out enemies, such as bandits, particularly those in camps with patrols or isolated sleeping bandits. The enemy camp along the western edge of Rocktower Pond is a good hunting ground.

Isolate and Alert: While sneaking, throw a rock to attract an enemy's attention, ideally making them move away from other enemies.

Confirm Alert Status: When the enemy investigates the rock, observe the white behavior hare on the top center of the screen. If it indicates the enemy is looking for you (shielding eyes and looking around), proceed.

Perform Stealth Takedown: Sneak up behind the alerted enemy, hold the "stealth kill" button, and when prompted during the struggle, press the button to kill them.

Achievement Pop: Upon successfully killing the enemy, the "Lights Out" achievement should unlock.
