Obsidian Hammer - Mortal Shell II Melee Weapon Guide

What is Obsidian Hammer in Mortal Shell II?

Obsidian Hammer is an unlockable piece of equipment whose name is independently exposed by the live Steam achievement set. The current launch map classifies Obsidian Hammer as a main melee weapon.

The achievement evidence proves that the item exists and can be unlocked; it does not by itself prove damage values, scaling, move properties, upgrade costs, or a best-build ranking.

Where do you find Obsidian Hammer?

Current launch-guide mapping places Obsidian Hammer as the reward for defeating the Prophet of Profane Infinities. Treat this as route guidance from the release build rather than an official API field.

If a patch changes the pickup, boss reward, gate, or dungeon layout, prefer the live game and the latest dated guide over an older route description.

Is Obsidian Hammer a weapon or sidearm?

Current launch checklists classify Obsidian Hammer as a melee weapon. That classification is stronger than guessing from the name alone and is kept separate from the Steam achievement evidence.

Should you upgrade Obsidian Hammer?

Test the weapon in the current build before committing scarce upgrade resources. Compare reach, recovery, posture pressure, crowd-control value, and how safely you can finish its basic sequence. Those practical traits matter more than an undated tier label, especially while launch balance patches are still changing equipment values.

See the weapons and sidearms overview, combat guide, and beginner guide before committing early materials.
