Quick Answer

Spirit Ashes are upgraded through Roderika’s Spirit Tuning service at Roundtable Hold. Most regular ashes use Grave Glovewort, while special ashes use Ghost Glovewort. For a first playthrough, do not spread upgrades across every summon. Build one durable ash and one damage or utility option first.

Unlock Checklist

StepActionWhy It Matters
1Meet Roderika around the Stormhill routeStarts the Spirit Tuning chain
2Reach Roundtable Hold and exhaust her dialogueMoves the unlock forward
3Talk to both Roderika and Smithing Master HewgTheir dialogue unlocks the service
4Rest and check near Hewg againSpirit Tuning appears once she relocates

If you are already at Roundtable Hold but cannot upgrade ashes, exhaust both characters’ dialogue until it repeats, then rest at the table grace.

Spending Glovewort

Player NeedSmart PriorityAvoid
First playthroughUpgrade one reliable tank summonRaising every ash by one level
Sorcery or ranged buildUse an ash that holds aggroChoosing only by damage

Glovewort is a route resource. The safe plan is to upgrade the summon you actually bring into hard fights, then wait until your build direction is clearer.
