Mortal Shell II — Unwieldly Stone: Charged Heavies with Kill-Time Healing

Published 2026-09-173 min read

The Unwieldly Stone powers a 35-Resolve charged heavy attack in Mortal Shell II and grants lifesteal stacks for every kill — up to five. Buy it from Merrick in Marrow Keep for 2,000 coins. Details and build advice inside.

The Unwieldly Stone is the survival Tarstone: a charged heavy attack powered by Resolve, plus lifesteal stacks that accumulate with every kill. For heavy-weapon builds that live in the thick of packs, it converts aggression directly into health.

Kills become healing — that is the whole business model.

How to buy it

  1. Head to Marrow Keep and speak with the merchant Merrick.
  2. Open the Tarstones tab of his shop menu.
  3. Select the Unwieldly Stone and pay 2,000 coins with a long-press confirm.

What it does

  • Activation: spend 35 Resolve on a charged heavy attack.
  • On kills: gain Leech stacks — up to five — each restoring health, massively extending your endurance in pack-heavy areas.
  • Upgrades raise the stacks earned per kill, so the snowball gets fatter as you invest.

Who it is for

Pair it with big, slow, crowd-clearing weapons — the Obsidian Hammer or the Great Martyr's Blade — where every charged swing threatens a posture break and every group is a full heal waiting to happen. Greedy front-line play stops being a mistake and becomes your regen rotation.
