 * Crippling Poison: Decreases Move Speed by 20% for 8 seconds.
 * Weakening Poison: Reduces Physical Attack by 10% for 6 seconds.

Stratagy and Tactics
Flash Cut will perform the charging slash as long as you still have the Evasion Boost buff given by Nimble Dash. The buff lasts for 3 seconds meaning that you can cast one or more other skills first.

At level 35 you can unlock the Evasion Master talent, extending the Nimble Dash's Evasion Boost to 5 seconds, giving more time to perform the charging slash. (unconfirmed, need to reach 35)

With enough cooldown reduction you can cast Flash Cut multiple times within the same Nimble Dash buff:
 * Two times with -6.25% cooldown or more.
 * Three times with -37.5% cooldown or more.
