Decided to exp in Ulegrande again since a long time. There were 0 Parties in the Area - while ToAU Areas you always have those special Parties not doing a search or just trying to sqeeze in.
Shortly before we Televazl I got Sanction Enhanced Food Duration and ate my Sole Sushi+1 right inside the town.
My bet on SE beeing not that evil/smart was right. After 1 hour had passed food was still active for a whole of 2hours.
So did I discover a neat little trick or does Food Effect sanction work anywhere anyway?
