[PBS Question] Improving Zoroark’s ability

I saw a thread recently asking about making an improved Illusion ability. But I can't find the thread anymore, has it had a solution? I thought I could add new abilities through the PBS but can't figure put how.

I would like it to increase the speed of the user while under the illusion, but it wears off when the illusion does, I think this was in the thread I saw before.

Is there anyone with experience in the PBS (and maybe scripting if that's required) who could help me?

You probably mean this thread.

Just FYI this is a scripting question rather than a PBS question—you can only change what abilities do via scripting.

Oh, so it hasn't gotten an answer... Dang, I was hoping I could find something, because no matter how many tutorials I watch I can't wrap my head around scripting and how everything works.

Thank you for showing me the thread!

It has gotten an answer now, it's actually pretty darn simple.
