Many Persona 5 players might not realize that they can craft the Eternal Lockpick, an unbreakable lockpick that eliminates the need to craft multiple lockpicks for locked chests in Mementos and Palaces. If you want to stop worrying about running out of lockpicks, this guide will show you how to farm the necessary materials and craft the Eternal Lockpick efficiently.

1. What You Need to Craft the Eternal Lockpick

To create the Eternal Lockpick, you will need:

• 20 Aluminum Sheets
• 10 Liquid Mercury

You can craft the Eternal Lockpick either by yourself or by calling Kawakami (if her Confidant rank allows her to do crafting for you).

2. How to Get Aluminum Sheets

Aluminum Sheets are much easier to obtain than Liquid Mercury. You can find them:

• In Mementos: Look for item cubes scattered around the floors.
• In Chests: Many chests in both Palaces and Mementos contain Aluminum Sheets.
• Enemy Drops: Some Shadows in Mementos occasionally drop Aluminum Sheets after battle.

Since they are common, you should collect them passively while exploring.

3. How to Get Liquid Mercury (Farming Anubis)

Liquid Mercury is harder to obtain and primarily drops from Anubis, a Shadow that appears in:

• Path of Akzeriyyuth (Mementos – Mid-Late Sections)
• Okumura’s Palace (Mid-Late Sections)

Best Liquid Mercury Farming Strategy:

1. Go to Mementos (Path of Akzeriyyuth) or Okumura’s Palace.
2. Find an area where Anubis spawns.
3. Farm Anubis by repeatedly battling in that area.
   • Move between floors to respawn enemies if necessary.
   • Some encounters may have multiple Anubis Shadows—this increases your drop chances.
4. Expect about a 60-70% drop rate for Liquid Mercury.
   • Not every Anubis will drop Liquid Mercury, so be patient.
   • The more Anubis you encounter at once, the better your farming efficiency.

4. Crafting the Eternal Lockpick

Once you have 20 Aluminum Sheets and 10 Liquid Mercury, check your crafting log in the Thieves’ Den.

1. Ensure you have the required materials.
2. Choose to craft the Eternal Lockpick.
   • You can do this yourself at the workbench in Café Leblanc.
   • If you have Kawakami’s Confidant Rank 7, you can call her to craft it for you to save time.

After crafting, the Eternal Lockpick will never break, meaning you can open every locked chest without worrying about crafting additional lockpicks.

5. Why the Eternal Lockpick is Essential

✅ Saves time and materials – No need to constantly craft new lockpicks. ✅ Ensures access to valuable loot – Never miss a locked chest in Palaces or Mementos. ✅ Makes late-game exploration easier – Especially useful when grinding in Mementos.

If you haven’t crafted it yet, make it a priority—it will save you time and effort throughout your Persona 5 playthrough!
