This question has probably been asked before, but here goes:
I have a green hag NPC who is going to attempt to pass herself off as our party druid's long-lost grandmother. I assume that via this spell, the hag can look (and even sound) like the druid’s grandmother.
Question: Would the druid's animal companion (a wolf) be able to use scent to pierce the evil hag's disguise? In other words, does Alter Self change how a being smells? I don’t see anything in the spell description about this.
