Since Sweet Scent has been implemented, perhaps Honey could be implemented too.
Possibly as a craftable item (with the new berry system), buyable item or item you can find (pickup).
For those who don't know, honey is pretty much a consumable which acts identical to sweet scent.
Cons:
- leppa berries might indirectly make this item useless, as 1 leppa berry = 2 sweet scents
Pros:
+ money sink
+ less tedious than using a leppa berry on sweet scent every so often
+ don't have to carry around a sweet scent user
