"Good luck!" in Cherokee, Maldivian and Aramaic

Hello.
I'm looking for someone who speaks Aramaic, Maldivian (Divehi) or Cherokee.
I have to know how to say and write (in its script) "Good luck!" in of these languages. I was looking for it on the internet but I didn't find it.

If you know how to say and write it, please answer. It's really important for me.

Thank you in advance. :)
