In addition to
wave of exhaustion, there's also a 3rd level
ray of exhaustion. Some of the Dungeon #100 casters have it, and the gauth from the 05/11/03
In the Works has it as an eye ray; the gauth description notes "no save", but it's not entirely clear whether that's gauth-specific, or
ray of exhaustion specific. Also from Dungeon #100 & the gauth (and the barbed devil),
scorching ray is 2nd level (IIRC), and apparently has no save.
I'd wager there's a
ray of fatigue out there somewhere; maybe 1st level?
PS: pech21, where is the confirmation of the change to SF/GSF on Andy's board? In
this thread, I see lots of discussion about it, but nothing from Andy either confirming or denying the change. (Admittedly, I tend to take that as evidence that it has changed, since saying, "There's a typo in the adventure" would be really simple . . . but it's not confirmation.)
