Fulminated Mercury


Highly precious grains forming the base for a devastating form of gunpowder.

Used in explosive Prosthetic Tool upgrades of advanced rank.

Created in secret by the Interior Ministry using knowledge from across southern seas. The central forces' military might owes much to this tiny tweak of chemistry.

Fulminated Mercury is a special Upgrade Material in Sekiro: Shadows Die TwiceFulminated Mercury is required for upgrading explosive Prosthetic Tools, and can be found in specific Locations or looted from specific Enemies.



Fulminated Mercury Usage



Where to Find Fulminated Mercury

  • Drops from Ministry Gunman in Ashina Outskirts.
  • Drops from Ministry Gunman in Ashina Castle.
  • Drops from the Gunmen patrolling the area at the Poison Pool Idol in Ashina Depths (Rare).
  • Drops from the gunmen behind Gun Fort Idol.
  • 2x can be found at the Hirata Estate near the second Juzou encounter (2nd Memory)
  • 1x can be found in Bodhisattva Valley behind a rock across an island with white monkeys,  in the poisonous water area.
  • 1x can be found in Ashina Outskirts after it is set on fire, near the Ogre, next to a canon.
  • 1x can be found in Ashina Outskirts after it is set on fire, at the top of the stairs where the original Ogre was.

Fulminated Mercury Notes & Tips

  • Players can only carry a maximum of 99 material\
  • Trvia --> The phrase "tweak of chemistry" in this item's description could be a reference to the Breaking Bad episode "Crazy Handful of Nothin'", in which the main character Walter White uses a modified form of fulminated mercury as a negotiating tool in securing the return of his friend's stolen drugs.
  • User experience --> Can be farmed with Bell Demon buff before getting locked out of Ashina Outskirts from Cannoneers in Gun Fort. From my attempts at this I gathered 4x from 20 runs with first loot increase in Monk tree and balloon. Hadn't even got a single one before that, I was mainly just getting some powder..
  • User experience --> After Ashina is ablaze, use the Ashina Outskirts - Stairway Idol , the Demon Bell Buff activated and a Mibu Balloon active, kill the Ministry Rifleman on the Tower, the two on the Ground and then follow 2 patrolling Ministry Soldiers towards Ashina Castle. You will have several Rifleman to kill and if you are fast, you can kill all of them with 1 Balloon. I received 0-1 Mercury each Run on average.

        I was in NG++ (patch 1.04) and did the shura ending so I didn't had access to the "ashina on fire" where most of it is. I had the skill "most virtuous deeds" and the ball active and farmed the guys on gun fort but they never droped it. I activated the bell demon and they started to drop it. So I guess without the bell demon they don't drop this iten. I also used the Golden Vortex and manged to farm the fulminated mercury very fast.

          After farming the gunmen by the gunfort idol for 2 hours and 15+ runs I'm pretty sure I can confirm they DO NOT drop without demon bell active. If anyone has had them drop without it and can confirm that it would be greatly appreciated.

            Should there not be another one tucked away on a ledge near the graveyard in Mibu Village? I think that’s the first one I got

                Farmed for over 2 hours behind Gun Fort with Demon Bell/Possession Balloon and 0x Fulminated Mercury dropped. Possibly doesn't drop from those mobs as of patch 1.03?

                  With the demon bell, a mibu balloon and both loot skill in senpou tree I got 2-4 mercury per balloon from doing runs in the Outskirts wall - stairway. Kill the dude in the tower, then the one below and then the one at the gate, climb to the roof and rest. 4-5 runs per balloon

                      The canon wielder near Old Grave idol drop them when Ashina is overrun. I was using Bell Demon, all skills and Golden Vortex. The one near the building where Blackhat Badger was did drop it for me.

                        Found 1x fulminated mercury in Ashina Outskirts right by where you fight the first ogre after it has been set on fire. I found it in NG+, so if someone could confirm if it's there on a regular NG, then that'd be great.

                          I am in NG+ at the last boss. I used Demon’s Bell curse and Mibu Possession Balloon, and went to Ashina Depths - Poison Pool. Backstabbed the gunner there and got 3 FM in 4 kills. Might have been crazy-good luck but got it in a matter of minutes.

                            I dropped it from normal riflemen/musketen/whatever scattered in the valley while having the Bell's Demon burden and the 2 drop perks in the monk skilltree

                              They drop pretty regularly from the ministry gunmen after getting the dragon tear. If you travel to the ashina outskirts - stairwell idol you can easily stealth kill 5 gunmen in less than a min then rest and repeat. I got 8 in maybe 10 mins or less.

                                For those interested, the riflemen at the gunfort will drop mercury *before* killing Owl. I have the Bell Demon and Rank 1 Virtuous Deed and they seem to drop it relatively often. I'm talking about five drops in twenty minutes worth of farming.

                                  Just got 2 fulminated mercury to drop (individually) from shotgun enemies in gun fort. I've only fought one battle on top of ashina castle (but the second one is there waiting for me), have the first item drop buff from skill tree, and bell demon buff is active. Shotgun enemies are also dropping yellow gunpowder now, but the mercury seems rarer as I haven't found any until now.

                                    It seems to be a surprise and a stretch to consider this a Breaking Bad reference. nevertheless is a welcome one

                                      Video for farming these effectively: Current description: Ashina Depths - Poison Pool idol, use Demon Bell and the green Mibu Possession Balloon for higher item drop rates, which lasts 4 full runs. This area changes after a certain boss, which will spawn these cannoneers. The drop rate is actually pretty good.

                                        I updated the page on Fort Idol. I have farmed this spot for a prolonged time and never received any Fulminated Mercury. I now killed Owl and went back to farm half a skill point, and two of them dropped in the span of 5 minutes. Proof: (two clips in one, two drops)

                                          Castle Outskirts - Stairway while it's on fire. There are three gunmen and a cannon wielder that drop Fulminated Mercury. One in the tower, one below the tower, one outside the gate, and the cannoneer is walking up the steps. Net experience: ~2700 for the four of them; Net sen (no balloon): ~400. The drop rate is about 7-10%.

                                            1. Ashina Castle idol after it's on fire. // 2. Equip Golden Vortex (fan upgrade). // 3. Pop balloon item+. // 4. Run to the stairs and use fan at the first steps, run up towards the middle of the 4~ enemies and use the Golden Vortex trying to hit as many as possible. // 5. Hold button to get the itens while running back to the idol. // 6. Repeat and profit.
