June's winning entry was written by Brent Newhall, for the June Contest: Lost Artifacts. He can also be found on his website Brent P. Newhall's Home(page) and twitter under @brentnewhall.
I hereby present the Bladed Sandals. These nasty little shoes have blades woven or otherwise worked into the sole, allowing a simple side-step to draw blood.
Item Slot: Feet
Property: When you shift, perform a free basic melee attack, dealing 1d6 + half level damage.
Now, give these out to a bunch of kobolds. This basically gives each kobold an extra basic attack every turn, provided there's a square for them to shift into. Watch your players tremble at the sight of kobolds again!
