So, a typical question I get from people learning "how to Druids" is this:
Can I turn into an animal and then cast Animal Growth on myself to become larger?
The answer, of course, is no, because Wild Shaping doesn't change your type (Aspect of the Wolf, however, is a different story, as well as a different type of cheese when paired with Animal Growth and Awaken).
Now, I was thinking over spells (I'm working on a handbook for Planar Shepherds as well as advanced Druid-ing in general) and was thinking about Enlarge Person.
When Wild-Shaped, you retain your type. Aka, most characters are still Humanoid...just a humanoid that happens to be, say, an Elder Viper Tree. Now, I know that if you cast Enlarge Person on yourself normally, it doesn't affect your Wild-Shaping abilities.
If, however, you cast Enlarge Person on yourself while Wild Shaped...what would happen? You would, per the spell, increase a size. If "you" were an Elder Viper Tree, however, then the way it seems to me is that "you" would increase in size, effectively increasing that Wild Shape size as well.
Once you left that Wild-Shape, everything would go back to normal -- well, you might still be a large/huge humanoid, but your next wild-shape would still be within normal boundaries (aka, not enlarged).
What I'm wondering is if my conclusion here is right. The other option is that the spell would somehow enlarge "the inner you" aka your humanoid form, bypassing your current form, but that seems to be really stretching the rules here.
What are your thoughts?
