HONE
    A weapon master is an individual who has dedicated himself to the
perfection of using a single weapon. In combat they are truly deadly with
their weapon, but such intense training causes them to become less
proficient with other weapons. Their skill is not complicated, but rather
focused and refined. Before a person can train as a weapon master
they must be full rank in the weapon they wish to master.

At rank 4 they may deflect ranged and thrown weapons by rolling under
4 X MD. They may also pick up their weapon in a pulse and use it with
only the loss of one attack.

At rank 6 they may fight defensively by decreasing their base chance to
hit by 10% for every 5% to defense they gain that pulse.
