Buy Stygian: Outer Gods The Heretic's Arsenal Pack as a Steam key at Gamesplanet.com

The Heretic's Arsenal DLC includes the following content:

• The Whisperer: Artifact. Protects your sanity, but makes you easier to notice. Despite its grotesque appearance, the creature seems harmless. Only its nightly whispers cause unease, their meaning fading into vague impressions by dawn.
• Bone Axe: Two-handed axe which consumes more stamina but swings a bit faster than Greataxe. Pure bone. Strong, smooth, and who knows from what. I found bone tools in the Himalayas once, but nothing like this.
• Kama: A curved, one-handed blade. Moderately fast and deadly. Traditionally, this is a Japanese agricultural tool, but I can’t picture it farming. Harvesting souls, perhaps.
