A Great Great Form Spirit of Earth? Fire?
They'd probably survive it, sure...but:
A) They wouldn't be happy
B) This would count as '
abusing a spirit' in my book (which leaves a stain in your aura)
C) Theoretically, the Dikote covering would only last as long as the spirit stayed manifested
D) there's no rules as to how Dikote would affect an item in 4e
E) It's just munchkin-like cheese being applied, so wouldn't pass the 1st of several vetting questions by my GM
