Also known as a hunga munga or danisco, this knife-axe hybrid consists of a hilt and blade that curves backward toward the wielder. The blade’s curve is such that, after a mambele has struck a victim, more damage is dealt as the weapon is extracted from the victim’s body.
Traits
Deadly d8: On a critical hit, the weapon adds a weapon damage die of the listed size. Roll this after doubling the weapon’s damage. This increases to two dice if the weapon has a greater striking rune and three dice if the weapon has a major striking rune. For instance, a rapier with a greater striking rune deals 2d8 extra piercing damage on a critical hit. An ability that changes the size of the weapon’s normal damage dice doesn’t change the size of its deadly die.
Disarm: You can use this weapon to Disarm with the Athletics skill even if you don’t have a free hand. This uses the weapon’s reach (if different from your own) and adds the weapon’s item bonus to attack rolls (if any) as an item bonus to the Athletics check. If you critically fail a check to Disarm using the weapon, you can drop the weapon to take the effects of a failure instead of a critical failure. On a critical success, you still need a free hand if you want to take the item.
Thrown 20 ft.: You can throw this weapon as a ranged attack; it is a ranged weapon when thrown. You add your Strength modifier to damage as you would for a melee weapon. When this trait appears on a melee weapon, it also includes the range increment. Ranged weapons with this trait use the range increment in the weapon’s Range entry.
Critical Specialization Effects
Source Core Rulebook pg. 283 4.0Certain feats, class features, weapon runes, and other effects can grant you additional benefits when you make a Strike with certain weapons and get a critical success. This is called a critical specialization effect. The exact effect depends on which weapon group your weapon belongs to, as listed below. You can always decide not to add the critical specialization effect of your weapon.
Axe: Choose one creature adjacent to the initial target and within reach. If its AC is lower than your attack roll result for the critical hit, you deal damage to that creature equal to the result of the weapon damage die you rolled (including extra dice for its
striking rune, if any). This amount isn't doubled, and no bonuses or other additional dice apply to this damage.
