Riders of Destiny
Unlike most glaives these weapons have a heavy ring or shpere counterweight on the butt end.
The Zeif Glaive is designed to be both used in combat on horseback and on foot. It has a large counter weight on the haft to balance against the weight of the blade. When used like a lance it is balanced to be used in one hand. On foot it can be used as a traditional glaive with reach or as a move action the wielder can switch up to using it as a double weapon without reach(treat the other end as 1d6 bludgeoning damage with a x2 critical multiplier) This is an exotic weapon.
