I assume that there will be appropriate messages for combinations such as fragrance A applied to sewage stinking person, fragrance A applied to clean person, fragrance A applied to clean high charisma person…etc. Possibly appended to current smell messages to accommodate for differences.
I can't imagine an expensive fragrance helping much applied straight after crawling out the sewers. However, I can imagine it making a character's smell message appropriately modified when they apply it when they are clean, to make them even more desirable...including temporarily increasing charisma.
The duration of the increase could vary depending on whether 'lasts 24 hours' etc special formulas or standard ones are used.
If you feel like doing some little coding/creating projects now, having just become a creator and all, may I suggest that TekSoft's room descriptions are fixed, as well the abysmal messages such as 'The manager opens his cubicle door shouting at the guards "Take that useless piece of shit out of here!", pointing at %N.'
The toilets are also not rooms, and the place is rather barren with the same description repeated all over. That isn't as important to resolve, but it would make sense to get TekSoft's rooms and messages up to Sindome's overall high standard.
