Balanced: A balanced weapon can be wielded more easily by smaller characters. A creature one size smaller than the weapon can use it in one hand. For example, a halfling could wield a balanced battleaxe in one hand.
Binding: This weapon prevents extradimensional movement by those it hits. Once per day, the wielder of a binding weapon may make a binding strike. On a successful attack, the target of the binding strike cannot move extradimensionally by any means, as though affected by the dimensional anchor spell. This effect lasts for 13 minutes. If the attack misses, the binding strike for that day is wasted.
Crazed: This weapon gives its wielder the ability to fly into a rage once per day as though affected by emotion (rage), but without the compulsion to fight heedless of danger.
Grasping: A grasping weapon is more effective when attempting to trip or disarm an opponent. It grants its wielder a +2 circumstance bonus on trip and disarm attempts. Disarm attempts made with grasping weapons do not provoke attacks of opportunity. Only melee weapons can have this ability.
Impact: Any bludgeoning weapon with this ability has its crit range doubled. For example, an impact quarterstaff scores a threat on a 19–20. This ability does not affect piercing or slashing weapons.
Ki Focus: This weapon serves as a channel for the wielder’s ki, allowing her to use any ki-based special attacks (such as a monk’s stunning attack, ki strike, and quivering palm, and the Stunning Fist feat) through the weapon as if they were unarmed strikes. Only melee weapons can have this ability.
Sweeping: This ability grants a +4 bonus on any Strength checks the wielder makes as part of an attempt to trip an opponent with the weapon. Only melee weapons can have this ability.
