The most common instinct an individual defeated in
battle, is to flee, to live again to fight another day.
Of course, if you hold the upper edge in a fight, escape is
the last thing you would want your foe to do. By carefully
using special techniques, one can hinder an opponent's attempts
to flee the field of battle. In order to execute this maneuver,
one must allocate 100% of his effort. This means he cannot
attack, or attempt to use spells or skills.
