Infada Stone
Taken from Antarctica by one of the sailors from the HMS Beagle to India, it was left to rest in a temple built deep in the Indian jungle. It was discovered recently by Tony, an explorer. He tried to kill Lara as she pursued him in an effort to recover the artefact along the River Ganges. He eventually retreated to the Caves of Kaliya where he met his demise.
Powers
The individual powers of the Infada Stone allow the bearer to levitate from the ground. The bearer may also manipulate energy from the atmosphere, and compress it into the forms of energy bursts and beams. The Infada Stone also imposes a state of madness on the bearer (as seen with Tony). To obtain the powers of the Infada Stone, the bearer must stab it deep through their heart.
When combined with the other crystal artefacts at the Meteorite Cavern, it will rapidly speed up the evolution of the bearer.
