The multiclass feat for wizards in the PHB says you gain a 1st level wizard at-will ability. Now, the cantrips in there are gained at first level, and they are at-will. I'm guessing that, since they aren't designated as 1st-level specifically, they don't count for the purposes of the feat and thus cannot be gained. Is that right? If so, is there any other way for a non-gnome to gain them? (Not hating on gnomes; I just know they can!)
Also, has anyone allowed this as a house rule? How has it gone?
