While a ranger using one blade to direct his fury at his
foe is impressive, a ranger using two or more, is ungodly. 
Proper training allows one to be able to direct his fury 
with his second hand weapon as well as his first. Even though
this seems difficult, its not as hard as it seems. Once one has
proficiency in bladed fury, hitting with the offhand proves 
relatively easy, since the opponent is already knocked off
balance from the hit from the primary weapon.
