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.
