Wizard's Wand

The Wizard's Wand is a device created by Cisco Ramon to combat Mark Mardon, nicknamed "Weather Wizard". The device sucks up excess electrons in the atmosphere, preventing any form of weather to occur, in order to fight Mark's atmokinesis. However, it can also be manipulated as a means to channel Mark's powers more precisely.

History
In order to easily fight the Weather Wizard, Cisco Ramon created the Wand. It was given to the Central City Police Department to place in the middle of the building if Mark came near. However, he shockingly appeared following its installation, catching them off guard. They were unable to use it and Captain Singh was paralysed, before The Flash sped in and used it to prevent the weather inside, making Mark flee. Then Barry restarted the timeline and captured Mark right away, so the device was never created.

When Mark returns and breaks both James Jesse and Leonard Snart out of prison, a new model of the Wizard's Wand was created by Caitlin Snow and Jay Garrick out of Barry's knowledge of the altered timeline in which Mardon created a tsunami to devastate Central City. After Cisco, Jay and Harrison Wells managed to send all of the bombs The Trickster gave kids while posing as Santa Claus into the breach, Barry shocked Mardon with the wand and defeated him.

Trivia
