Weeping Stone is an Infusion Tarstone you buy from The Collector — a night-only merchant just south of the Abandoned Outpost Beacon — for 1,500 Coin, and it infuses your Sidearm to inflict Trauma.
Weeping Stone is an Infusion Tarstone in Mortal Shell 2 that turns your Sidearm into a Trauma-dealing tool. You will not find it in a chest — it is a shop purchase from a merchant who only appears after dark, and like every Tarstone it scales through four levels once you have unlocked the right upgrade bench. Here is exactly where to buy it, what the infusion does, and how to push it all the way to a permanent effect.
Where to get Weeping Stone in Mortal Shell 2
| Detail | Value |
|---|---|
| Type | Infusion Tarstone |
| Sold by | The Collector (night only) |
| Location | South of the Abandoned Outpost Beacon |
| Cost | 1,500 Coin |
| Slot | Sidearm |
Fast-travel to the Abandoned Outpost Beacon and head straight south — The Collector’s stall sits a short walk down from the beacon, and Weeping Stone is on offer there for 1,500 Coin. The one catch is timing: this merchant only appears while the world is in its night state, so if the stall is empty when you arrive, you will need to swap the world over to night before The Collector turns up. Come back after dark and the stone is yours to buy.
If you have seen an older listing point you toward a “Deserted Slums” area, ignore it — the vendor and the stone are tied to the Abandoned Outpost region, not the slums.
What Weeping Stone’s Trauma infusion does
Weeping Stone is an Infusion-type Tarstone, which means it slots onto your Sidearm rather than a melee weapon, and while it is equipped your Sidearm shots inflict Trauma. That makes it a natural pick for any build that leans on ranged pokes — instead of your Sidearm being pure chip damage, every shot starts stacking a status effect, so the ranged part of your kit contributes to breaking an enemy down rather than just softening it.
Because the effect rides on the Sidearm slot specifically, it pairs cleanly with a gunplay-forward loadout: you keep your melee Tarstones doing their own job while the Sidearm carries the Trauma. On its own the infusion is limited-use at first, which is where upgrading comes in.
How to upgrade Weeping Stone to level 4
| Level | Effect |
|---|---|
| Level 1 | Sidearm shots inflict Trauma |
| Level 2 | Trauma infusion lasts 4 shots |
| Level 3 | Trauma infusion lasts 8 shots |
| Level 4 | Trauma infusion becomes permanent |
Key Every Tarstone, Weeping Stone included, climbs through four levels, and the payoff is uptime: you start with a plain Trauma proc, then the infusion lasts 4 shots at level 2, 8 shots at level 3, and finally becomes permanent at level 4 — no more re-applying it mid-fight.
Before you can upgrade any Tarstone, you have to open up that option at the Tarforge in Marrow Keep. You do this by handing Franz the Etching Needle, a quest item you pick up out in the world; giving it to him expands the Tarforge so it can enhance Tarstones at all. Once that is unlocked, the upgrade itself has two costs. First, the stone has to earn Tarstone experience, which it only does while it is actually equipped — so slot it and play with it rather than leaving it in your bag. Then, once it has enough experience banked, you spend Coin at the Tarforge to push it to the next tier. Repeat that cycle — earn experience, pay Coin — up to level 4.

Frequently Asked Questions
Does using Weeping Stone cost Resolve to activate?
The 1,500 Coin you pay The Collector is a one-time purchase price, not an ongoing cost, and it is separate from any in-combat resource. Activating the infusion does not cost 20 Resolve per use; the infusion is tied to the Sidearm and applies Trauma directly.
Where is the Etching Needle you need to upgrade Tarstones?
The Etching Needle is in a chest just before the Magdalena, the Lady of the Woods boss fight. You reach it past The Tarblighted Shepherd, and when you spot Ruk across the bridge, turn to find a small side area with a bone chest holding the Needle. If it is not at that location on your run, check the Glutted Mire, inside the Corrupted Gate dungeon near the Sunken Village beacon. Either way, once you have it, take it to Franz at Marrow Keep.
The Collector won’t be at the stall in daylight — switch the world to night before making the trip south from the Abandoned Outpost Beacon, or you’ll arrive to an empty spot.
