Find all five Mortal Shell 2 Tarforge upgrades for weapons, sidearms, Tarstones, material refunds and the late level-cap increase.
Muradean Actuator: weapon upgrades
Open the chest immediately inside Village Outskirts Beacon in Disciple’s Path. Bring the Muradean Actuator to the Tarforge in Marrowkeep to unlock melee weapon upgrading.
Obsidian Lathe: sidearm upgrades
Travel southeast from Widow’s Overlook Beacon to Martyr’s Tomb and loot the rear-room chest. The Obsidian Lathe controls sidearm ranks, not melee weapon ranks.
Etching Needles: Tarstone upgrades
In Glutted Mire, progress beyond Sunken Village and The Wandering Shepherd route. The chest near Ruk’s former position before the regional boss contains Etching Needles.
Foundry Stone: remove and refund
Find the Foundry Stone south of Outskirts of Mammon Beacon near the enemy group at the castle-wall gate. It lets the Tarforge remove weapon and sidearm upgrades for Gloom and return the materials.
Endless Core: raise the level cap
Inside The Hidden Nave Beacon in The Unfound Path, pass through the fog twice, pick up the torch and escape the fog section. The chest contains Endless Core, which opens weapon and sidearm levels +17 and above.
Bundle the upgrade lanes
The equipment archive separates melee upgrades, sidearm upgrades and Tarstone tempering. Recover the Muradean Actuator for the first Tarforge lane, find the Obsidian Lathe before planning sidearm ranks and collect Etching Needles before spending Tar cores on a permanent stone.
