Mortal Shell 2 Zhirelle Guide: Shell Bond Upgrades & Memories

Updated Aug 31, 2026 锝?The Shellkeeper at Marrow Keep's entrance
馃幆 TL;DR: Zhirelle stands at the Marrow Keep entrance behind the Beacon and upgrades your Shells with Glimpse. Commit to one or two Shells early 鈥?Glimpse is not refundable.

1. Where to Find Her

2. What She Upgrades (per Shell)

UpgradeWhat it does
Bond TierUnlocks the next tier of that Shell's passive abilities
Shell Points capacityRaises how many passives you can run at once
Shell Revive EfficiencyImproves the health a Shell returns on revive
MemoriesPlayable story sequences that expand the Shell's ability set
馃挕 Note: Shell Points themselves come from leveling the Harbinger with Gloom at any Beacon, not from Zhirelle. You can allocate and reset those points at a Beacon or in her room 鈥?respeccing is free.

3. Don't Buy Shell Location Markers

Zhirelle can mark any undiscovered Shell on your map for 3鈥? Glimpse. Skip these. Every Shell is reachable through normal exploration (see our Shells guide), and Glimpse spent on markers is Glimpse taken from your bonds.

4. How to Spend Glimpse on a First Run

  1. Pick your main Shell early 鈥?the investment is permanent
  2. Clear the first Memory of any Shell you intend to keep 鈥?it locks the Shell in and opens its ability tree
  3. Raise Bond Tier on that Shell first 鈥?higher tiers gate the strongest passives
  4. Bank the rest for New Game Plus 鈥?Shells carry over
鈿狅笍 No refunds: A single playthrough doesn't produce enough Glimpse to max every Shell, and spent Glimpse cannot be refunded. Don't spread it thin.
馃幆 Bottom line: "Commit to one Shell, clear its first Memory, max its Bond Tier, bank the rest." Zhirelle is where your Shell gets stronger 鈥?but only if you invest deliberately.
