The weapon you touch becomes an instrument to cull the weak from the battlefield.
Any living creature with HD equal to or less than 7 must succeed on a Fortitude save or die if struck in combat with this weapon. Spell resistance does not apply against the death effect.
In addition, the wielder gains the benefit of the Cleave feat as long as he holds the weapon. If he already has the Cleave feat, he gains the Great Cleave feat instead. If he already has the Great Cleave feat, he receives no additional benefit.
Augment: For every additional spell point you spend, the weapon can affect a creature with 1 more HD.
