Well, the Fay Boars might make progress if used with Mass Flight; that day, pigs would fly.
Sorry, just had to.
(Pork: It's what's for dinner, every day and every night because our thrice-cursed quartermaster has fay boars. I guess it might be better than broth day in and day out.)

It'd be nice if Fay Boars were stealthy, so that they could be kept OUT of the combat when the army they're supplying goes into battle. You could then attach them to a stealth Vanahearse and they'd keep out of trouble, as opposed to stampeding into the emeny and getting killed by the flaming plasma death flying around.
