PSA: The Scent of Marr and Breath of Solusek are sold on vendors
 

For 1pp or so, on a vendor in East Commonlands no less (among other places). I keep seeing people auctioning these for 20 to 50pp. At my level that's smaller change but I imagine there are lower level mages getting burned by this, whether or not the people selling them are aware of their availability.

The people's champ!
