One of the problems with putting all of your strength and weight into a single
swing is that, should you miss, you are off-balance and unprotected. Knights
know this, and plan their strategy accordingly.  This skill is all about
timing. When a knight is fighting a foe that becomes momentarily incapacitated
and unable to defend or retaliate, he may use this skill to strike with
maximum force. Any weapon may be used for this skill.
Note that some weapons work better against some creatures than others. Arms lore may help.
