Good question.Cwreando wrote:It was my thought that the polymorph spell allowed any creatures form to be taken as small as a hummingbird and as large as 2000 pounds. Thus a small elemental or up to 2000 pounds based on the spell description. Are you using a more finite limitation for the spell?
That is correct, but the way I read the spell description, it contemplates that natural/corporeal forms only be taken, so things like elementals, spectres, will 'o wisps etc. would not be permitted. Many of these creatures have no mass, so they are "smaller" than a hummingbird and also rely on magic to exist and move -- and the spell does not grant the user the magic abilities of the target, only the physical form.
Make sense?
A frost giant would be permitted, but it weighs over 2000 lbs -- 2800 to be exact.

(I don't have OSRIC in front of me, but do not think the weight changed between editions.)
