Beastiary 1

[Valix Bloodlord]

If I am using "WILD SHAPE" as a DRUID, and I use WILD SHAPE/ ELEMENTAL BODY IV (4), and turn into an EARTH ELEMENTAL. Do I get "Tremor Sense". The text in the CORE RULE BOOK under elemental body reads, "See Beastiary 1" for abilities. Which abilities do we use out of Beastiary, how does this work. We are all experienced players and we need clarification on this rule. Thank you.

You get only what the spell list in the individual elemental section and its natural attacks. Since it does not list Tremor Sense you don’t get it.

[Vatras]

As written, you don't get tremor sense. Under the polymorph section of the magic chapter you can see that you lose all your special senses (like darkvision or scent), but they may be restored, if the new form has them also. That says you don't get senses you don't already have.

The spell itself does not grant special senses either, except darkvision.

[Bloodrealm]

None of the Elemental Body spells say that you gain sensory abilities from the forms other than Darkvision 60, as Vatras said.
