Prompt abilities will always pop first against ones that are not, and your interrupt is a prompt ability.

In your case, your interrupt should always land first against pretty much any jutsu out there, unless the ninja you're trying to kick is in the 1st/higher position and/or has a higher initiative rating.

Against stats, you really can't do much. The only thing you can do is to improve your initiative rating or mess around with your positions if that is the problem.

Like the previous poster said, you have to delay using the interrupt until you see an icon above their head.

It just requires practice.

If you still can't get it off, then it means you cast it too early/late, have lower initiative, or are in a lower position than the said person you're trying to interrupt. This post was last edited by Godsu* at 2016-8-23 00:03
