Penumbra is an item in Bastard's Wound.
Your shadow flickers erratically in the wan violet light emitted by this viciously-sharp bronze blade, fluctuating between converging about the weapon's length and stretching as if trying to escape its presence. No legend sings of this weapon, yet it bristles with sorcerous energy the sharpened alloy edge seems insufficient to contain. Perhaps the craftsperson responsible for this sword used techniques long lost to modern smiths, infusing it with a power that may be older than the Archons, the Overlord, or even the Oldwalls you discovered it in.
