Flashing Blades

Acquisition

 * Lou, of the Knives (Shenzun Tunnels)
 * Waeng (The Undercity) (Only during the Assist the Guards quest.)

Usage Notes
With sufficiently high Dagger Mastery, an assassin can have this skill constantly active, to keep received attacks to a minimum.

If used in conjunction with critical defence 100% block can be maintained when attacking, if a critical hit can be guaranteed every 8 seconds
