Mortal Shell 2: Nightgrasp Stone Location (Phantom Infusion)

The Nightgrasp Stone is the Tarstone that puts Phantom on your weapon in Mortal Shell 2, and it is locked behind an offering chest rather than dropped by an enemy. You will not be able to open that chest on your first approach. It sits in a stone building past the Abbey Entrance area and stays sealed until three separate candles in the surrounding area have been lit.

Quick answer: Travel from the Outskirts of Mammon beacon to Abbey Entrance, continue to Sester’s Refuge, then cross the bridge to the stone building. Light one candle inside the chest room, one on the cliffside pillar just outside, and one further down the lower cliff path, then open the chest.

Nightgrasp Stone: Type, weapon slot, and Phantom effect

Nightgrasp is an Infusion Tarstone, so it slots into your primary weapon and spends Resolve to coat that weapon in Phantom for a limited number of strikes. Infusion stones are not universal. Only one weapon in the game accepts this one, the Black Needle, so grabbing it is only worth prioritising if that weapon is in your rotation or on your shortlist. You can have two infusion stones equipped at once.

Route to the offering chest from Outskirts of Mammon

Fast travel to the Outskirts of Mammon beacon and head toward Abbey Entrance. The path drops down a series of ledges, and most of the enemies along it can be run past rather than fought.

Fight through the stone ruin to reach the Abbey Entrance beacon and cleanse it. This is the checkpoint you want active before the offering puzzle, because the candle run involves enemies on a narrow cliff path.

Push on into Sester’s Refuge, the area marked out by its red foliage, clearing or dodging the enemies on the way through. Reach the beacon there and cleanse it as well.

Cross the bridge past the beacon. A combat trial triggers here with waves of enemies, and clearing it puts you directly in front of the stone building that holds the chest.

Note: There is a breakable wall behind the stairs earlier on this route. Smashing it opens onto a sarcophagus holding the Tyrant’s Stone, which is worth grabbing while you are passing through.

Where the three candle offerings are

Interacting with the chest before you start tells you how many offerings are still missing, and that counter is your progress tracker. Lighting the first candle drops it to two, and the chest only unlocks at zero.

Enter the building and interact with the chest to register the puzzle. The first candle is in the same room, so light it before you go back outside.

Step outside and look for the stone pillar on the cliffside close to the building. The second candle sits on it, and it is the shortest detour of the three.

Follow the path further down the cliff. Enemies are stationed along it, and the third candle is at the end of that lower route.

Head back up to the building and open the chest. The Nightgrasp Stone is inside.

How to confirm the chest actually opened

You will know it worked when the chest no longer shows an offerings requirement on interact and simply opens, followed by the Nightgrasp Stone appearing in your inventory under Tarstones. If the prompt still lists offerings needed, one candle did not register. The usual cause is walking past a candle without triggering the interact prompt during a fight, so retrace the cliffside route and check the pillar and the lower path again.

Upgrade levels at the Tarforge in Marrow Keep

Upgrading is where this stone gets genuinely useful, because the top tier removes the strike limit entirely. To unlock those tiers you need the Etching Needles, looted from a bone chest shortly before the Magdalena, the Lady of the Woods fight. When you spot Ruk past the bridge, drop through the opening and turn right before the tunnel to find the small side area with the chest. Hand the needles to Franz at the Tarforge in Marrow Keep to expand the upgrade options.

Level	Effect
1	Consumes Resolve to infuse the weapon with Phantom
2	Infusion lasts for 4 strikes
3	Infusion lasts for 8 strikes
4	Infusion is permanent

The exact Resolve cost and strike counts shown in the item description have shifted between builds, so treat the numbers on your own tooltip as authoritative. The progression itself does not change, and the final tier always makes Phantom permanent.

Levelling it is passive work rather than a currency dump. Equip the stone, kill enemies until the experience bar on it fills, then return to Franz and pay the Coin cost for the next tier. Repeat that until Phantom stops eating Resolve altogether, at which point the Black Needle keeps the infusion up without any upkeep.
