Elemental manipulation

"He can influence the elements - water, earth, fire, and air. He is able to physically manipulate the world around him with his will, similar to telekinetic powers."

- Entry on Benjamin's gift

Elemental manipulation, also known as element manipulation, elemental control, and atmoskinesis, is Benjamin's power to control the four elements of nature - earth, air, water, and fire with his mind.

This is the most powerful physical ability and one of the most powerful gifts in general that ever existed among vampires, and therefore highly coveted by Aro. Therefore, Amun, who created Benjamin, tried to keep him secret from the Volturi, fearing that he would be taken into the coven.

Benjamin has not yet gained full mastery over this power and it is unknown if/when he will ever be able to control it completely.

Description
This power works by Benjamin's will to manipulate natural elements (Water, Fire, Earth and Air), and to channel it through his hands to call on the elements in his surroundings. It also seems to work by him sensing the elements in his surroundings and then manipulating them.

In battle, fire would be a devastating weapon against other vampires.

Limitations
Although this gift is extremely powerful, it is useless against psychic attacks, the best example being his attempt to halt Alec's advancing "mist" using wind and creating a fissure in the ground, using gravity to blow away the mist with no success; this proved ineffective because the mist was only an illusion, and not a physical attack. This makes Benjamin vulnerable to mental powers, and, if not moving fast enough to defend himself, he could easily become an open target.

Origin
Benjamin manifested this power as a human, though he could only control fire at that time, and could barely use it.

His power's manifestation began with fire before he started manifesting the other three. In battle, fire would be a devastating weapon against other vampires.

Breaking Dawn
"He can actually influence the elements of nature - earth, wind, water, and fire. True physical manipulation, no illusion to the mind."

- Edward' description of Benjamin's gift.

Benjamin practices his power at the Cullens' house by creating geysers from the nearby river and creating gusts of wind. On another occasion before the confrontation with the Volturi, he telekinetically moves a collection of boulders into an area accessible to him in case he has to use them to fight. On the last occasion, he creates a fissure in the ground, and a strong gust of wind to try and halt the advancing "mist" effect of Alec's power, though both of these attempts fail.

In the movie, Benjamin first uses his power to create a watery wall, then earth and air to provide entertainment to Renesmee. He later uses fire to start a bonfire and bond with the other vampires. In Alice's vision of the battle, he opens a huge rip in the ground, sending multiple vampires and shape-shifters falling into the underground lava.
