Good points, @Dr_Ruminahui and @AbdulAlhazred. FWIW, the only reason I chose the magic item prices as the ritual cost of Raise Dead is that it's a wealth chart that already scales by level; there's no new chart to include or math to do this way. If you want to raise a 13th level character, it costs as much as it would to buy a 13th level magic sword; if you wanna raise a 4th level character, it costs as much as it would to buy a 4th level magic implement. It definitely will affect the character's wealth, but at least this way it's consistent. I'm of the opinion that if the adventures are being tailored to the characters properly, the lost wealth will be recovered in the long-run anyway.
