How to Upgrade Tarstones

Franz

Every Tarstone can level up to 4 times, growing stronger or shifting into a new effect. To upgrade, give Franz the Etching Needle: Allows players to enhance their Tarstones when they give it to Franz at the Marrow Keep. Quest Item.

Level 2 upgrades cost coins, but you'll also need enough experience first. Just equip a Tarstone and rack up kills to earn EXP toward its next level.

Where to Find the Etching Needle

Find the Etching Needle inside a chest just before the boss fight against the Magdalena, Lady of the Woods. Past the Tarblighted Shepherd where you meet Ruk, turn right to spot it.
