My desk broke while testing this. This is your fault.
Also, sorry for taking so long to do this. I meant to get it done sooner, but I had to go somewhere for the weekend, so I wasn't able to, and then I completely forgot about it for a while.

Conclusion: In Gen 3, all overworld abilities work when a Pokemon is encountered with Sweet Scent. In Gen 4, Magnet Pull and Static seem to not work outside of battle with Sweet Scent. In Gen 5, Static doesn't seem to work outside of battle with Sweet Scent. In Gen 6, Magnet Pull and Static seem to not work outside of battle with Sweet Scent.
Also, if there's any specific area you would like me to test these in or an ability you would like for me to test again, let me know and I will, if possible.
Still trying to get Pressure and Intimidate tested.
