BATTLESPHERE 'BATTLE SPHERE

BATTLESPHERE
Syntax: cast 'battlesphere'
 
 Blademasters may use this mantra to enter a light trance allowing
them to empty their minds of most distractions and focus on the 
immediate sphere of battle around them.  Doing so enables them to
aim with greater accuracy, and be better able to avoid spells cast
at them.
