what is siphon fortnite

In Fortnite, Siphon is a game mechanic that allows players to restore health and shields by either killing or dealing damage to other players. Depending on the game mode, players can instantly heal health or shield upon eliminating an opponent. Siphon was introduced as a Limited Time Mode solo game-mode in Fortnite: Battle Royale and the second daily LTM game-mode in December 2018. While it was initially a limited-time mode, it has since been added to the core game modes.
