Treasure/Possessions: Triple Standard
Extract (Ex): A brainstealer dragon that maintains a hold with a tentacle for 5 consecutive rounds extracts the opponent's brain, instantly killing that creature. This power is useless against constructs, elementals, oozes, plants, and undead. It is not instantly fatal to foes with multiple heads, such as ettins and hydras.
Improved Grab (Ex): To use this ability, a brainstealer dragon must hit a creature up to one size category larger than itself with a tentacle attack. It can then attempt to start a grapple as a free action without provoking attacks of opportunity. If it wins the grapple check, it establishes a hold and begins to extract the opponent's brain. A successful grapple check each round furthers the extraction process and deals automatic tentacle damage. A brainstealer dragon can hold one creature in each tentacle, but it cannot grapple an opponent with more than one tentacle. An opponent can escape with a single successful grapple check or an Escape Artist check.
Mind Blast (Sp): This psionic attack is a cone with a length appropriate for the dragon's size (as breath weapon). Anyone caught in the cone must succeed on a Will save or be stunned for 1d4 rounds plus the dragon's age category. The save DC is Charisma-based. Once the dragon uses this ability, it cannot use it again for 1d4 rounds.
Telepathy (Su): Brainstealer dragons can communicate telepathically with any creature that has a language within 100 feet.
Skills: Bluff, Gather Information, and Survival are considered class skills for brainstealer dragons, in addition to the standard class skills for dragons.
This subtype usually is used for elementals and outsiders with a connection to the Elemental Plane of Earth. Earth creatures usually have burrow speeds, and most earth creatures can burrow through solid rock.
