Valor Mortis Guide: Hidden Chapter 2 Health Flask Upgrade in the Quarry

The Quarry at the end of Valor Mortis’ Chapter 2 hides a Ferrofluid Flask Power Upgrade on its upper cliffs. You can see the scaffolding from the Lantern, but you can’t reach it on your first pass through the Valley of Ashes. The route runs across crane hooks and hanging crates that only respond to the grapple. That ability arrives at the end of Chapter 3, so this upgrade is something you come back for once Chapter 4 is underway.

Quick answer: Once you’re in Chapter 4, rest at the Quarry Lantern and ride the elevator up. Then grapple and pull your way up the cliff to a red chest guarded by an armored swordsman.

Requirements for the Quarry Ferrofluid Flask Power Upgrade

Every part of the climb depends on the grapple. Get these in place before you fast-travel back.

Finish Chapter 3, which unlocks the grapple. It becomes usable from Chapter 4 onward.
Activate the Quarry Lantern in the Valley of Ashes to make it a direct travel destination.
Open the Quarry elevator shortcut. It isn’t strictly required, but it saves you the first climb.
Be ready for snipers, riflemen, wall-crawling monsters and one heavily armored melee enemy along the way.

Quarry route to the hidden flask upgrade chest

The route is a straight vertical climb with a few fights along the way. Grapple points show up as blue rings, and the hanging crates display a PULL (HOLD) prompt when you aim at the node underneath them.

Go to the Quarry Lantern, the hourglass rest point marking the close of Chapter 2. Rest there to refill your Ferrofluid Flasks before beginning the climb.

Lower the wooden elevator shortcut beside the Lantern, then ride it up to the Quarry’s upper level.

Taking the Elevator Shortcut — The elevator shortcut takes you straight to the upper Quarry, where the grapple route begins. Shown at 00:42 in NewDengs’s video. Image: One More Level

At the top, walk past the ladder to the edge beside the elevator and turn to face the gap. Aim at the blue grapple ring on the swinging crane hook and grapple across to the wooden beam platform on the far side.

Look up at the blue node under the hanging wooden crate and hold the pull button until the crate drops all the way down. Jump on, and it carries you up to the next section when it’s released.

Take out the snipers covering this level, then grapple straight ahead to the next ledge. A Nephtoglobin Vial sits on this stretch.

Ascending to Upper Scaffolding — Once the snipers are down, grapple to the next ledge toward the upper scaffolding. Shown at 01:24 in NewDengs’s video. Image: One More Level

Find the second hanging crate above you and pull it fully down. Jump on and ride it up to the wooden platform above.

Take out the foe stationed on the platform, then unlock the ornate red chest. It contains Pure Blade Material rather than the flask upgrade, so continue onward.

To your right, collect the Oil Grenade from the narrow wooden beams. Continue across the broken walkway, clearing riflemen and wall-crawling monsters until you arrive at a cliffside clearing.

Defeat the heavily armored enemy with a two-handed sword guarding the cave alcove. It stays out of view as you approach, so expect it to engage as soon as you enter the clearing.

Open the ornate red chest beside the candles in the alcove to collect the Ferrofluid Flask Power Upgrade.

Use the zip line next to the alcove to slide back down to the Quarry floor. That spares you the climb down and drops you near the Lantern.

Confirming the pickup and applying it at a Lantern

After opening the chest, the pickup notice displays Ferrofluid Flask Power Upgrade and a count of 1. The item has no effect just by carrying it. Rest at any Lantern, then enter the Upgrade Ferrofluid Flasks menu to spend it on flask potency. The healing increase takes effect there.

Power Upgrades raise how much each flask heals, and Empty Ferrofluid Flasks add extra charges. The two use separate materials and don’t stand in for each other.

Ferrofluid Flask potency levels and upgrade costs

A base Ferrofluid Flask restores 50 Health, and every potency level adds 10 more. The first level takes one Power Upgrade. After that, each level costs more, so this Quarry chest carries more weight than a single item suggests.

Potency upgrade	Healing per flask	Power Upgrades needed	Running total
Base	50	—	0
Upgrade 1	60	1	1
Upgrade 2	70	2	3
Upgrade 3	80	2	5
Upgrade 4	90	2	7
Upgrade 5	100	3	10
Upgrade 6	110	3	13
Upgrade 7	120	3	16
Upgrade 8	130	4	20
Upgrade 9	140	4	24

Chapter 2 already gives you two Power Upgrades in chests, one near the Guidepost Lantern and one in the Military Camp. Adding the Quarry one brings you to three, which is exactly enough for Upgrade 2 and 70 Health per flask. Reaching the cap of 140 takes 24 in total.

Chests aren’t the only source. Louis’s Laboratoire stocks one Power Upgrade from the start of the game for 3,000. It adds another to stock from Chapter 5 (Crime) and a third from Chapter 9 (In Ruins). Two more come from conversations. Chests holding them are spread across the Fortress, City of Orphans, University, Valley of Ashes, Fallen Village, Caverns, Vale of Wrath, Cursed Hollow and The Outskirts.

Other loot on the Quarry climb

The route also hands out a handful of supplies and one weapon material. All of it is on the path you’re already taking.

Item	Where on the climb	Use
Nephtoglobin Vial	Ledge after the first crate	Refills Nephtoglobin
Pure Blade Material	First red chest	Blade upgrades
Oil Grenade	Wooden beams to the right	Throwable
Pistol Ammunition	Along the route	Pistol rounds

You can carry up to three Nephtoglobin Vials, so a full reserve leaves this one behind. Pure Blade Material goes into the Saber, Rapier and Claymore from weapon level 5 upward. Each blade needs one at level 5, two at level 6 and three at level 7.

Once the Quarry chest is open and the upgrade is spent at a Lantern, you’ll see the new healing value every time you drink a flask. The zip line back down means the whole detour takes only a few minutes from the Lantern.
