Atop the Shoulders of Giants
The Spiritfire Blade
This small dagger appears ancient and ornate. Its sheath and hilt are red, and adorned with mosaic etchings. When unsheathed the dagger is revealed to have no blade, but rather spouts a gout of shimmering fiery energy, concentrated into a long line.
When used on an enemy this weapon’s “blade” passes clean through the enemy’s armor (and body) as though they were no impediment at all, causing severe lacerations (internal and external) where it passes, as well as burning the exterior surface area of any objects or creatures it touches.
The knife detects with a powerful evocation aura.
The knife also seems to possess some manner of intellect which is possessed by extreme fear and a constant sense of fight-or-flight.
