Kpinga (3.5e Equipment)
From D&D Wiki
The Kpinga is a strange weapon used by distant tribes. It looks like a Kama about 21 inches long, but that's where the weapon similarities end. At the "head" of the weapon, a long scythe-like protrusion juts out, backed by two more blades at a 45 degree angle to the blade at the top, both of which are an inch long. The area below these two blades is also sharp, running most of the length of the weapon, down to its 3-inch handle. Jutting out from the handle at another 45 degree angle is a fourth blade with a rounded tip. Near the intersection of the blade and the handle, a semicircle is formed on the blade. This gives the blade an appearance not unlike graffiti you might find drawn in a foggy window at a high school.
 Weapon Mastery (Kpinga) (3.5e Feat)
In addition to the simple effects listed above, people truly trained in the kpinga unlock new abilities with it as they progress in levels. These people are said to have mastered the weapon and its use.
- 1 HD: You gain proficiency with the kpinga
- 5 HD: You may use a kpinga to make a trip attack. If you are tripped during your own trip attempt, you may drop the kpinga to avoid being tripped.
- 10 HD: You may use a kpinga to make a ranged trip attack. You cannot be tripped during your own trip attempt when using a kpinga in this way.
- 15 HD: If a thrown kpinga hits its target, it can ricochet towards another target of the thrower's choice (within five feet of the original target). The thrower may make a second attack roll against the new target, albeit at a -2 penalty.
