Petrification (Su): Whenever a blackstone gigant damages an opponent with a slam attack, that creature must make a Fortitude save (DC 26) or be turned into a statue as per the spell flesh to stone cast by a 20th-level caster.

Trample (Ex): As a standard action, a blackstone gigant can trample opponents at least one size category smaller than itself. This attack deals 8d8+25 points of bludgeoning damage. A trampled opponent can attempt either an attack of opportunity at a -4 penalty or a Reflex save (DC 43) for half damage.

Animate Statue (Su): A blackstone gigant can use one or more of its attacks to touch and animate any creatures it turned to stone with its petrification power. This ability works like an animate objects spell cast by a 20th-level caster, except that the petrified creature can be of any size. The animated stone statue has the statistics of an animated object of its size and composition, with a hardness of 8. Typical petrified creatures have the improved speed ability (bonus of 10 feet for two legs or 20 feet for more legs). All such animated objects are under the mental control of the blackstone gigant or its creator (giving orders to a statue is a free action). Such statues remain animated for 20 rounds. A blackstone gigant cannot animate a petrified creature more than once, and it often destroys statues after the duration of its animate statue ability expires.

Construct Traits: A blackstone gigant is immune to mind-affecting effects, and to poison, sleep, paralysis, stunning, disease, death effects, necromantic effects, and any effect that requires a Fortitude save unless it also works on objects. The creature is not subject to critical hits, subdual damage, ability damage, ability drain, energy drain, or death from massive damage. It cannot heal itself but can be healed through repair. It cannot be raised or resurrected. A blackstone gigant has darkvision (60-foot range).

Skills: Blackstone gigants have a +8 racial bonus on Climb checks and can always choose to take 10 on Climb checks, even if rushed or threatened.

A blackstone gigant enters melee fearlessly, wading in among smaller opponents with its trample ability and then flailing about it with its many arms, hoping to petrify as many foes as it can. It then animates any statues it created and orders them to attack. Should the animated statues be too weak to aid in the fight, the blackstone gigant often destroys any foes it petrifies, preventing them from being returned to flesh during the battle.
