Fighters trained in unarmed combat learn this powerful technique of
closing in and forcing the battle into a brutal, close-quarters struggle.
A successful grapple often drags the fight to the ground unless the
target proves too quick to evade.
While grappled, it becomes difficult for a victim to flee, weapons are
clumsy and suffer penalties, spellcasting is nearly impossible, and most
forms of parrying, blocking, or even some magical protection are disabled.
Be warned, however: wrestling with a dagger specialist or an assassin can be
a painful mistake.
