In this video, you shall learn four things:
 - Preventing Skill from running if Timed Attack fails
 - Setting a Skill to be Critical if the Timed Attack is preformed well enough
 - Changing the Animation of the Skill based on the result of the Timed Attack
 - Changing the Action Sequence used based on the result of the Timed Attack

Hope you enjoy and hope this answers all questions about how you can add extra features using Timed Attacks.
