Reaper

Reaper is a Specialization featured in Battlefield 1, introduced as part of the Apocalypse expansion. It is an "Affliction" specialization, with the effect that immediately after the player spawns, they lose 1 health per second. Killing a player halts the drain temporarily, resuming after ten seconds. The player cannot replenish their health from medical crates or bandages when using the specialization, meaning the only way to survive indefinitely is to kill another player once within every ten seconds.
