Mortal Shell II — Acolyte's Stone: Charged Light Attacks from Merrick's Shop

Published 2026-09-173 min read

The Acolyte's Stone adds a Resolve-fueled charged light attack to your weapon in Mortal Shell II, scaling to +15% crit chance and 150% crit damage. It costs 2,000 coins at Merrick's shop in Marrow Keep — details inside.

The Acolyte's Stone gives your weapon a new verb: a charged light attack, powered by Resolve, that scales into a genuine critical-strike engine. No trial, no boss — it simply costs 2,000 coins at the Marrow Keep shop.

Two thousand coins buys your weapon a whole new attack.

How to buy it

  1. Travel to Marrow Keep and find Merrick, the merchant NPC.
  2. Talk to him and open the Tarstones tab of his shop.
  3. Select the Acolyte's Stone and pay 2,000 coins.

What it does

  • Activation: spend 40 Resolve to unleash a charged light attack.
  • Level 1: the charged attack gains +15% critical chance.
  • Level 2: it deals 150% critical damage.
  • Level 3: the Resolve cost drops to 30, making the move spam-friendly.

Why it is worth the coins

Charged attacks slot into any rhythm: open a duel with one, answer a boss's recovery with another, or bank them as burst between parry punishes. The crit scaling means it rewards every other crit-boosting piece you own, and the level 3 discount turns it from a finisher into a habit.

If your style runs heavier, its sibling is the Unwieldly Stone — the same idea, built around charged heavy attacks and kill-time healing.
