An Arcane Stave is a larger conduit through which magical energy is channeled to produce an offensive effect, similar to a Wand but larger and requiring two hands to use (though it may be wielded in  one hand with the offhand kept free). Their appearance may vary but they  are generally between 30 to 60 inches.  Arcane Staves deal a set amount of damage per Mana invested when  attacking with it, depending on the weapon Quality. They have a 5 second  Concentration time to attack with regardless of damage dealt. The Range  of an Arcane Stave increases with Quality as well, and Arcane Staves  are the only Armament that require a Glyph to grant Proficiency with it.  A Character may only spend up to 25% of their total Mana, rounded down,  per attack with this weapon.
