One VALORANT player on Reddit recently discovered that Skye flashes may be canceled out by the player flashing themselves.
VALORANT has become famous for having multiple flashes that seem to last an eternity. Several agents have flashes in their kits, and players are doing whatever they can to reduce the intensity of the flashes.
The other player must also be playing Skye in order to cancel the Skye flash; otherwise the trick will not work. As shown in the clip, the enemy Skye engages the flash, effectively flashing herself, thus canceling out the enemy flash.
This flash cancellation technique hasn't been patched yet with other agents than Skye. There are also agents like Yoru, KAY/O, and Phoenix who have throwable flashes. However, these agents are different from Skye, who may not be able to cancel out enemy flashes as Skye can.
