Your healing flask in Mortal Shell 2 is the Mether’s Pulse, a rechargeable consumable that runs dry after a few uses. It does not refill from executions or pickups. Instead, you top it back up by visiting the tall, cone-shaped stone Beacons scattered across the world.
Quick answer: Rest at any Beacon and back out of its menu. Your Mether’s Pulse charges return to maximum (for example, 5/5) the moment you leave the menu.
Refill the Mether’s Pulse at a Beacon
Beacons are the large, dark stone monuments that mark key points on the map, such as Disciple’s Grotto. Reaching one and interacting with it is all that is needed to restore your healing flask.
E to revitalize the Beacon. A bright white light triggers, and the location name appears on screen with a “BEACON FOUND” prompt.
Resting at a Beacon also restores your HP and Resolve, so it doubles as a full reset before a tough fight.
How to confirm it worked
Check the flask charge counter after you close the Beacon menu. A number that read 1/5 before resting will show 5/5 once the refill goes through. If the count is back at maximum, the Mether’s Pulse is ready to use again.
Note: Resting at a Beacon revives every enemy you defeated in that area. Plan for a fresh set of foes on the way out, and refill only when you are ready to clear the path again.
Increase how many charges you carry
Refilling always returns the flask to its current maximum. To raise that maximum, you upgrade the Mether’s Pulse using two materials, both of which are consumed at a Beacon.
| Material | Effect when consumed at a Beacon |
|---|---|
| Revered Gland | Improves Capacity, giving you more Mether’s Pulse charges per refill. |
| Synaptic Vessel | Improves Efficiency, increasing how much each use of the flask does. |
Both items can be found out in the world, and a limited supply is sold by Merrick at the Marrow Keep. To apply them, rest at a Beacon, open the Mether’s Pulse option, then choose Improve Capacity or Improve Efficiency and confirm. A notification such as “MOTHER’S PULSE CAPACITY +1” confirms the upgrade landed.
None of these upgrades are missable. If you skip one, you can return for it after the final boss during free roam, before starting New Game+.
The short version: is simple. Reach a Beacon, revitalize it the first time by holding E, then rest and exit the menu to send the Mether’s Pulse back to full. Feed it Revered Glands and Synaptic Vessels over time, and each refill will hand you more healing than the last.
