Philosopher's Stone

The Brahmastra, commonly known as the Philosopher's Stone is an ancient artifact used by Savitar and later his avatar Alchemy. It is the first ever artifact responsible for the creation of meta-humans in ancient times. It can also shoot powerful blasts of energy, fast enough to hinder a speedster. Alchemy used it to return powers people once had in Flashpoint Timeline as servants of Savitar.

History
The Brahmastra, known colloquially as the Philosopher's Stone, is an ancient stone in Hindu mythology believed to be responsible for the creation of the first meta-humans.

At one point Savitar used it to become a metallic being and the first ever, as well as the fastest, speedster, through which he became connected to it, using it to travel between multiverses to hire new meta-humans to his cult, as well as to kill other speedsters who stood in his way before conquering a world. However, a future Barry Allen somehow trapped him in the stone, buried in a temple in the past leaving Savitar trapped as a result.

After having a hallucination of his sister, Julian Albert went on an expedition to find it. He found it after weeks of searching, but was transformed into Alchemy and became a servant of Savitar as a result. For years following, he began blacking out and taking the form of Alchemy, which was Savitar controlling his mind while he had no memory of the events.

In late 2016, Alchemy first appeared in Central City, stepping out of the shadows, having accompanied the Rival, and threw Barry back with a beam from the stone.

The team infiltrated Alchemy's lair and Alchemy thoroughly beat down Barry with an army of beams from the stone. Wally couldn't resist temptation and touched the stone and it encased him in a cocoon-like container. Once Savitar appeared and killed the cops present before attacking the Flash, which allowed Alchemy to escape with the Stone.

It also appears that Savitar may be contained in the stone, as Julian states that he blacked out after touching the stone, and became Alchemy afterwards. However, the exact connection or relation between Savitar, the Brahmastra and the Speed Force has yet to be revealed. Each time the stone was encased in it's mysterious container, Savitar would vanish from the physical dimension. After using the Stone to talk to Savitar through Julian, Barry and Jay use their speed to open a portal into the Speed Force, throwing the Stone inside as a means to trap it and Savitar forever.
