Correct me if I'm wrong, but you can't buy crossbows in Sigrogana. This seems like a huge oversight, because crossbows are easily bought in Korvara! They're everywhere! You can't walk into a smithy or arm-dealing establishment on the entire island without one of them being on offer.

Na Alee in Tannis seems like a good NPC for the purpose of selling the fabled SKI-scaling bow.
