"Free Action" skill?

[GameDevMike2020]

Maybe it is that I am so tired I am missing something obvious, but I am hoping that the rest of the community can help out here. I am trying to make a certain skill (or more accurately, set of skills) take no time to activate, effectively making them "free actions" ala Dungeons and Dragons. I have not yet finalized my decision about whether to utilize turn based combat or a time progress model, so if you happen to have a solution that works with either, double awesome points and gratitude to you! Thanks in advance for any help you can offer with this problem.
