Fulminated Mercury

fulminated mercury upgrade material sekiro wiki guide

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 (雷汞, Raikō) 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

Starts to drop from the members of the Sunken Valley Clan, once Time of Day in the game has advanced to evening. While farming, you have to have the effect of the Demon Bell ("Sinister Burden") active, for the following enemies to drop the material:

Notable locations are the Gun Fort in Sunken Valley and at the Poison Pool in Ashina Depths.

After Ashina Outskirts and Ashina Castle have been set ablaze, the material also drops from the following enemies there:

Furthermore, there are seven Fulminated Mercury to be found in fixed locations throughout the game:

  • 1x in Bodhisattva Valley, behind a rock across an island with white monkeys, in the poisonous water area
    (Note: This is the earliest one you can get)
  • 2x at the Hirata Estate, near the second Juzou encounter (second Memory)
  • 1x in Ashina Castle (after set ablaze), halfway up the main staircase to the castle, in an alcove on the right
  • 1x in Ashina Reservoir (after set ablaze), behind the Seven Ashina Spears miniboss
  • 1x in Ashina Outskirts (after set ablaze), near the Ogre, next to a cannon
  • 1x in Ashina Outskirts (after set ablaze), at the top of the stairs behind a set of boxes where the original Ogre was 

 

Fulminated Mercury Notes & Tips

  • Players can only carry a maximum of 99 material\
  • Trivia --> 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 an intimidation tactic to secure payment for the drugs Tuco stole from his partner. After destroying the thief's office with and receiving his money, the thief asks him what he used to create the explosion. He answered "fulminated mercury - a little tweak of chemistry". 
  • 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 --> Second the above post, but with both Monk tree increases, balloon, and Demon Bell averages 1+ per run. There are 2 gunmen at the bridge to take, 3 gunmen (1 tower 2 ground) and a cannoneer after passing through the gate (back toward Outskirts), and another 3 gunmen (all tower) and a cannoneer as you near the final shrine. 10 chances at this; it goes quickly and can all be done in a single balloon if you’re fast.
  • 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.
  • User experience --> (Tested in NG+) With Demon Bell active and Most Virtuous Deed, go to the Ashina Castle Idol once Ashina is ablaze and look to the stairs. There are 3-4 riflemen (signified by the gun on their back) and each has a chance of dropping a Fulminated Mercury. It takes as little as 20-30 seconds to kill them, rest, and repeat, and it took me at most 10-15 minutes to get 8 Fulminated Mercury. Note that I did not use Mibu Balloons, so this could go even faster.
  • User experience --> Drops from the Cannon enemies in Ashina Depths, near the Poison Pool idol. Appears to be a rare drop, found this out by farming them. Starting from the Poison Pool idol, go up the wall and backstabbing the 1st Cannon enemy. Grappling across the trees to the right of him to the 2nd Cannon enemy and drop kill him. Finally grapple using the closest tree to the right, and you drop behind or close to the 3rd and final Cannon enemy. Grapple up and drop back to the idol, rest, and repeat. Earned 3 in about 3-4 mins
  • User experience --> The Cannon enemies before the Gun Fort idol began dropping this after the Guardian Ape Boss was defeated. Multiple farming runs before that produced yellow gunpowder as a rare drop and no Mercury. After the Guardian Ape was defeated, the loot tables seemed to shift, either because of the boss itself, or obtaining the final last prosthetic tool from the Ape but the loot table shifted before the tool was installed. The new loot table seems to provide yellow gunpowder fairly often, & Fulminated Mercury rarely (at about the same rate as yellow gunpowder dropped before defeating the Ape).
  • User experience --> Farmable from the ministry soldiers at the ashina castle idol once Ashina is ablaze.   Using Mibu possession balloon and golden vortex prosthetic tool, sneak up behind the group of ministry soldiers with golden vortex loaded and unleash the vortex.  You probably can do 2-3 runs from the idol on a single possession balloon, and should be able to get at least one fulminated mercury.  I was able to farm more than a dozen in <30 minutes using this method.

      Didn't need Most Virtuous Deed to get the two Fulminated Mercury I needed within 10-15min, just Virtuous Deed, Demon Bell & Balloon at the Gun Fort.
      Pre-Divine Dragon btw

        You don't have to kill the Apes, I have only fought them and the Cannon-types in Gun Fort are dropping this already, rarely. I farmed the area extensively before fighting the Guardian Ape and they never dropped it, now, after just fighting but not defeating the Ape, the items are dropping in the same farming area.....

          The trigger for the cannoneers to start dropping cooler things is acquiring the Mortal Blade, not killing the Guardian Ape. Hope this helps

          • easiest farm lategame for this seems to be ashina outskirts - stairway idol (where you fought chained ogre). Spawn after Ashina is on fire, kill the gunner in the tower, drop, kill the guy below, kill the gunner past the gate, then the cannon guy and ds3 dex user. If you want better chances, or some adamantite scrap as well, push forward and farm the rest of the guys in the area you fight the juzou clone. slow, but yields lots of xp, sen, and rare upgrade materials like yellow gunpowder and fulm. mercury and adamantite scrap.

              So I can confirm that the cannon guys near the Old Grave at Ashina castle in the towers do indeed drop them alomg with yellow gunpowder. I haven't beaten the Guardian Ape yet but I have the Mortal Blade and the stone withoit Kuro's charm (I honestly don't know how that works or if it helps in that regard) Bell Demon and both levels of good virtue or whatever it's called. It does take a while to get but it does drop from them

                The amounts needed for the different upgrades all need updated. Only a couple reflect the actual amounts needed.

                3x for Leaping Flame (wiki has 1 listed)
                3x for Great Feather Mist Raven
                3x for Purple Fume Spark (wiki has 2 listed)
                3x for Suzaku's Lotus Umbrella (wiki has 2 listed)
                3x for Lazulite Sabimaru (wiki has 4 listed)
                3x for Lazulite Axe
                3x for Lazulite Sacred Flame (wiki has 4 listed)

                These are the correct amounts found on the Prosthetic Tools page in-game. Someone with edit capability needs to fix this.

                • Got some from Shotgun dudes at Gun Fort Idol. Demon Bell on, Most Virtuous Deeds (lvl2), Genchiro dead, Guardian Ape dead. Bloodsmoke Ninjitsu equipped &gt; Gun Fort Idol &gt; walk up and backstab deathblow the guy &gt; Bloodsmoke &gt; backstab the other shotgunner &gt; walk out &gt; backstab the 3rd shogunner &gt; run back and reset.

                    This needs editing. Suzaku's Lotus Umbrella only requires 1x Fulminated Mercury to upgrade to, bringing the total needed for all upgrades to 18.

Earned 3 in about 3-4 mins This is perfect and confirmed: -Latest version of the game on Steam -Before the ashina fire (i still don't know the events). -Just killed the Guardian Ape first time. (madaf...) -I rang the Demon Bell. -No Mibu Possession Balloon, i got none and didn't try whit it, let us now. -I Have both Sempou greed skills activated. Fulimanet Mercury x4 in ~30mins (~20 runs). Slow but... the item is there! &lt;3

                        I can confirm that this drop starts from Gun Fort cannon dudes after collecting the flower/stone/mortal blade... &amp; same with Grave Wax from bell taro in Mibu Village. However even with the bell demon and possession balloon it was a ***** and a half to get it to drop like farming Slabs from Darkwariths in the New Londo Ruins in Dark Souls.

                          Patch 1.04, confirmed dropped from the gunmans ( both the big and small gunman) near Gun Fort Idol with Demon’s Bell actives. Got 4 Fuminated Mercury in 2 runs.

                            Best tactic is the golden vortex one, spam the***** of out this on the riflemen at ashina castle stairs (ashina castle idol) while they fight the ashina samurais! Got five fulminated mercury in one run!

                              No luck while farming the two gunmen behind the gunfort idol, NG+ with demon bell and possession balloon active. Was trying it for a solid hour with no results. Beginning to think that you possibly need to be beyond a certain point in the game? Only explanation I can think of excluding ridiculously bad luck.

                                  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

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.

                                                        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.

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)

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%.
