Scorpion the poisonous polearm

Scorpion the poisonous polearm <red glow>

Description:	This polearm looks like a long spear with a wide, jagged point. A set of four spikes eminate from the back of the polearm's head, sticking straight out from the shaft of the weapon. Just below these spikes is a small hatch that opens into a small hollow spot in the weapon. While this does not seem to harm the weapon or reduce its strength, it seems like an odd thing to have. It is too small to hold much.
