10 Coolest Weapons In The Arrowverse
4. Philosopher’s Stone
The Philosopher's Stone was a powerful weapon in the Arrowverse, and has been used in a variety of different ways throughout The Flash series. The stone is made up of speed force energy and can be used to take on speedsters such as Barry Allen, while also having other properties.
It is used by villains Dr Alchemy and Savitar during the third season of The Flash, as the stone is used to bring help the metahumans of the Flashpoint timeline (such as Wally West) regain their powers that had been lost when Barry fixed time. The stone has also been used to nearly kill Barry, as Alchemy has used the stone's fast firing rate to take on the speedsters.
While being powerful enough to restore the powers of metahumans, it has also been used to possess people so that Savitar can speak through them, and the stone had the ability to help Savitar appear in the real world whilst still being trapped in the Speed Force.
Fans also have the stone to thank for the creation of Savitar's powerful suit of armour and the creation of Kid Flash, and while it no longer exists post-Crisis, the stone will forever go down as one of the most powerful and coolest weapons in the Arrowverse.
