Axe of the Dwarvish Lords
Aura strong conjuration and transmutation; CL 20th
Slot none; Weight 12 lbs.
This is a +6 keen throwing goblinoid bane dwarven waraxe. Any dwarf who holds it doubles the range of his or her darkvision. Any nondwarf who grasps the Axe takes 4 points of temporary Charisma damage; these points cannot be healed or restored in any way while the Axe is held. The current owner of the Axe gains a +10 bonus on Craft (armor, jewelry, stonemasonry, traps, and weapons) checks. The wielder of the Axe can summon an elder earth elemental (as summon monster IX; duration 20 rounds) once per week.
The Axe of the Dwarvish Lords rusts away to nothing if it is ever used by a goblin to behead a dwarven king.
