Firewalker is a Player Modification first seen in the Library in Season β20, which causes a player to leave Instability in their wake when they leave a Location.


When a player who is a Firewalker leaves a Location, they will leave Instability in their wake. Essentially, when a Firewalker leaves one Team to another Team, their former Team will become Unstable.
