Hi,

You might notice that a preview shown recently dealt with new occurence of terminology :

Summoning Circle F74

... X is the number of A icons on the characters knelt for the cost .... I do'nt understand what it means. ... A new entry for the FAQ ???

Yeah, this is just an instance of a Game of Thrones term creeping over into Cthulhu. You would not believe how often this happens, and how many we remedy during playtesting. Looks like this got missed. "Knelt" = "Exhaust"

I'm guessing there will be errata.
