Hi all i have a question about a fiction / mechanic

example :

If I take a move that swap a stat “when you do…. use cold, hot , dark instead of…”

I must roleplay the stat to make it work? Or simply work cause the move say so?

Example: i take from the ghoul skin , the move “disaffected: when you turn someone , roll with Cold” i must make some special fiction to justify the fact im using Cold instead hot? Or not?

Thx to all’ and sorry for my bad english 🙂
