The demon rune is an item in Doom (2016) which occurs only during multiplayer and SnapMap game play. It appears as a floating red pentagram with a set spawn point. It transforms a player into one of several powerful demons when touched.
When taken, the player who obtains the demon rune will be transformed into a demon they selected before the match. In multiplayer, this transformation lasts for a total of 60 seconds, after which the player will revert to his or her human form if they have survived. Although each demon is powerful in its own right, it is possible for enemy players to kill the player who has become the demon, and doing so will cause the demon rune to drop, where it can be collected by any other player to transform and lay waste to his or her enemies.
The demon rune will otherwise eventually respawn, with its reappearance announced verbally to all players in the game 15 seconds beforehand with the message, "Demon rune spawning in 15 seconds."
In SnapMap, the demon rune has no time limit, and the player will not transform back into a human unless they are either killed or are affected by a trigger in the map which changes the player race value back to human. Respawning behavior, if any, is under the control of the map author.
The demons currently available for use, in order of unlocking for the base game, are listed below. One demon was added in each of the three downloadable content packs for the game, but these are now unlockable by all players since the v6.66 update.
|Demon||Source||Unlock level||HP||Primary skill||Secondary skill|
|Revenant||Base game||1||300||Twin missiles||Jet pack|
|Baron of Hell||Base game||5||750||Grab attack||Ground pound|
|Mancubus||Base game||9||800||Rockets||Vent heat|
|Harvester||Unto the Evil||21||350||Shoot lightning||Detonate|
|Cacodemon||Hell Followed||36||500||Bile spew||Tongue skewer|
Note that as of v6.66, only the revenant, baron of Hell, and mancubus are available in SnapMap. The demon type used by a player is under the control of the SnapMap's author in that mode.
