Because it's not cool when a party of six tenth level adventurers dies to six of them without dropping a single one.

Impale (Ex): Whenever a battlebriar succeeds a grapple with a Medium or smaller creature, there is a chance that the creature will become impaled on one of the thorns. After the grapple has begun, a battlebriar attempts another grapple check as a free action to impale the creature on its thorns.
An impaled creature is helpless until it beats the battlebriar in an opposed grapple check. As long as the only creatures that is is grappling with are impaled, a battlebriar is not considered grappled. When making grapple checks against impaled creatures, a battlebriar takes a -20 on grapple checks.
Improved Grab (Ex): To use this ability, a battle briar must hit with its slam attack. It can then attempt to start a grapple as a free action without provoking attacks of opportunity.
Thorn Volley (Ex): Battlebriars grow and shed their thorns at an incredible rate, and by rearing up on their hind legs and snapping their bodies forward, they can launch a deadly volley. As a standard action, a battlebriar can launching a volley of thorns, centering the volley anywhere within 30' The thorns deal 5d6 points of piercing damage to all creatures within a 10-foot radius (Reflex DC 22). The save DC is Strength-based.
Trample (Ex): Reflex half DC 22. The save DC is strength-based.
Thorn Field (Ex): The thorns on a battlebriar protrude into the area surrounding the creature, causing several effects on creatures moving through a battlebriar's threatened area. A battlebriar can make up to four attacks of opportunity each round. (Unlike the Combat Reflexes feat, this ability does not allow a battlebriar to make attacks of opportunity while flat-footed.) In addition, the DCs for Tumble checks to move through a battlebriar's threatened area or through the squares that it occupies increases by 10. Creatures three or more size categories smaller than the battlebriar cannot not move through the area that it threatens.
Skills: *Despite its size, a battlebriar blends well with its surroundings, and it gains a +8 racial bonus on Hide checks in aboveground, natural environments.
