The back of this dark cloak depicts a silver spear pointed downward.

The wearer of a piercer cloak can make devastating attacks when positioned above her enemy. When you activate a piercer cloak, any attack you make on your current turn from higher ground (PH 151) deals an extra 1d6 points of damage. If you charge your enemy from at least 10 feet above him, this extra damage increases to 2d6. This benefit lasts for 1 round.
This ability functions three times per day.

Lore: When the Halfling Rain came to Holtberg—the seven nights when halfling thieves pounced from rooftops onto passersby, assassinating them or knocking them out and taking every last stitch they owned—many of the thieves wore these cloaks (Knowledge [history] or Knowledge [local] DC 15).
