Would that be using Eloween or Wyler's modifiers?
DM's call, obviously, but for the sake of giving a quick answer, I'd say you'd be able to use Wyler's stats, but with Advantage since the check involves tracking a scent, or you can have Eloween look herself.
Heck, if the DM is particularly nice, you might get both~ xP
In any case, Here's Ferrin's roll, though I doubt it'll be of much use. He's gotten his good rolls out of the way already, I suppose~ xP
