Energy Drain Abyss Gear location in Crimson Desert
The Energy Drain I gear is not directly found as a standalone item—you’ll obtain it from a weapon hidden in a secret cave. This cave is located in the Lost Song Cave area in Demeniss, just above Serpent Marsh, specifically near a waterfall positioned toward the top-right section of the map.

Reaching the cave is the main challenge, as the strong waterfall current will push you away if you try to enter normally. You’ll need to carefully climb up the surrounding terrain and approach the entrance from the correct angle.
The key here is timing and movement precision, as the entrance requires you to push through the water force using a mobility skill.
How to get Energy Drain Abyss Gear in Crimson Desert
Step 1
Climb up the rocky terrain surrounding the waterfall until you reach a position slightly above the cave entrance. This gives you the right angle to attempt entry.

Step 2
Position yourself carefully and prepare your movement ability—specifically the “thrice attack.” This ability is crucial to bypass the force of the waterfall.

Step 3
Use the thrice attack to pull yourself into the cave opening in one fluid motion. If done correctly, you’ll bypass the pushback effect.

Step 4
Once inside, locate the treasure chest placed within the cave interior. The area is small and easy to navigate.

Step 5
Open the chest to obtain the Demenissian Hero’s Musket, which already has Energy Drain I installed.

At this point, you’ve successfully acquired the Abyss Gear—but it’s still attached to the weapon.
Extracting and embedding Energy Drain Abyss Gear into your weapon
To truly benefit from Energy Drain I, you’ll want to extract it and apply it to your preferred weapon. This process requires visiting a specific NPC. Here is how you can extract and reuse the abyss gear for any weapon:

Step 1
Travel to the lake located south of Silver Wolf Mountain. In the middle of this lake, you’ll find a small, isolated house, Bari Witch’s house.

Step 2
Enter the house and interact with the witch NPC inside. She provides special gear-related services.

Step 3
Select the “Extract Abyss Gear” option and choose the Demenissian Hero’s Musket. This will separate Energy Drain I from the weapon.

Step 4
Once extracted, navigate to your inventory and select the weapon you want to enhance.

Step 5
Embed Energy Drain I into the weapon, provided it has an available slot. If not, you can create a socket to accommodate the gear.

This flexibility allows you to tailor the perk to your preferred combat style, whether you use bows, firearms, or hybrid builds.
Why Energy Drain I is worth getting early
Energy management becomes increasingly important as you progress through Crimson Desert. Running out of arrows or ammo in longer fights can put you at a disadvantage, especially in boss encounters or extended exploration sessions.

Energy Drain I effectively reduces downtime and resource dependency, letting you maintain pressure on enemies without constantly restocking. This makes it particularly valuable for players who prefer aggressive or sustained combat approaches.
It also pairs exceptionally well with fast-kill builds, where frequent enemy defeats trigger continuous resource recovery.
