Warcaster

Warcasters use Staffs and specialize in using water, fire, earth, and wind magics to siege the enemy. A singe warcaster is worth an army of solders when it comes to raiding a castle. They imbued their Staffs to the brim of its capacity before they start transform the stored Mana from within, than they cast the spell they wish from the Staffs, making sure the almost overloaded Staffs only expels from this point on, as the spell will surly explode in the Warcaster's face. As the spell is casted, both versions of the spell is combined, making for a devesting attack that normally couldn't have been made possible. The downside of Warcasters is that they take a long time in-between attacks as they need to absorb ambient mana for both themselves and the Staffs, making absorbing twice as long, unless of course the Staffs is self absorbing.
