The earth subtype says that earth creatures usually have burrow speads, and earth creatures with burrow spead have tremorsense. So does a druid or caster who used elemental body to turn into a earth elemental form gain tremorsense because they gain the burrow spead, or is the tremorsense limited to those with the earth subtype?
I think that according RAW a druid is actually completely blind when gliding thru the earth.
Yes, but I've seen other threads from James Jacobs that has indicated that they should be able to. So when I saw that about the earth subtype, I thought it might have been an easy way to fix the lack of detail.
