Those ability scores are pretty good, I think.
Something unique, or just give them contagion (modified to a single target in 10 ft)?Once per day, they can cause disease; to use this ability, they need merely to point at any victim within 10 feet.
Change shape or alternate form to birds Tiny or smaller?Three times per day, shan sao can polymorph into the shape of a bird. (Note the flying speed above.) They usually assume the forms of crows, ravens, or other common birds native to the immediate area.
Borrow from outsiders?Once per day, they can summon 1-3 tigers within a half-mile radius, provided tigers are in this area. These tigers arrive in 1-6 turns. The animals fight for the shan sao and can understand the humanoids desires and needs. The tigers remain with the shan sao for up to a full day, although they will leave earlier if no longer needed.
