How to get Obsidian Hammer
- Reach Obsidianite Mines on the Mammon side of the campaign.
- Defeat the Prophet of Profane Infinities.
- The hammer is the encounter reward — not a side chest.
When to use it
- Week 1 described a full balance pass so the hammer 'hits substantially harder.'
- Still a specialist. If you wanted a usable heavy without the animation tax, take Great Martyr's Blade first.
Before you leave
- Do not judge this weapon on a pre-Week 1 video.
All eight names: Axatana · Axe & Dagger · Veteran's Battle Axe · Great Martyr's Blade · Black Needle · Clockwork Scythe · The Iconoclast.
