Have the option to KO players and keep their body as a slave. The player would just respawn no different than a regular death. Higher level and better equipped players give higher quality slaves. Player slaves expire after 24 hours, on the captor’s death for any reason, or on the NPC slave’s death. You can’t take a PvP slave if you are enslaved. You can only be enslaved by one player at a time, otherwise you just die instead of getting KO.
Special roles available for player slaves.
