To turn a pebble into a stone golem,
A) Would it not work at all because stone golems have immunity to spells affected by SR?
B) Would it work but the Golem would not be immune to spells and could be dispelled because it's a spell effect?
C) Would it not work because you cannot turn a non-magical item into a magical item with the spell?
D) Would it be better just to make the pebble into an elder earth elemental or something else like that?
