Conan Exiles Isle of Siptah Dedicated Server Setup
The Isle of Siptah expansion introduces a radically different map to Conan Exiles, featuring the massive magical Maelstrom storm system, vaults, and Surges of Power mechanics that periodically flood the map with powerful NPC waves. Setting up a Siptah dedicated server differs from the default Exiled Lands configuration in several important ways.
🌪️ Maelstrom Events
Siptah's Maelstrom is server-side driven. The storm's intensity and duration are configurable; poorly tuned settings can spike CPU usage by 300% during a full Surge event.
📦 Extra DLC Requirement
All players joining a Siptah server must own the Isle of Siptah DLC. The server itself does NOT need a separate DLC key: it switches maps via configuration only.
Switching to Isle of Siptah
The Siptah map ships with every dedicated server download, so there is nothing extra to install. The simplest switch is the map path as the first launch argument, ahead of the other switches:
/Game/DLC_EXT/DLC_Siptah/Maps/DLC_Isle_of_Siptah -logOr set it as the default map in Engine.ini; a map given on the launch line wins over this:
[/Script/EngineSettings.GameMapsSettings]
; Exiled Lands, the shipped default:
; ServerDefaultMap=/Game/Maps/ConanSandbox/ConanSandbox
ServerDefaultMap=/Game/DLC_EXT/DLC_Siptah/Maps/DLC_Isle_of_SiptahMaelstrom Performance Settings
The Maelstrom is the Storm family of keys in ServerSettings.ini, under [ServerSettings]. These are the shipped defaults:
[ServerSettings]
StormEnabled=True
StormCooldown=105
StormDuration=15
StormMinimumOnlinePlayers=0
StormBuildingDamageEnabled=False
; storm creatures
ElderThingsEnabled=True
ElderThingSpawnRate=1.0
MaxAmbientElderThings=700
MaxSiegeElderThings=5
MaxAmbushElderThings=200To cut the storm's NPC load on a small server, lower the three Max...ElderThings caps. StormTimeWeekdayStart/End and StormTimeWeekendStart/End (HHMM, 0000 to 2359 by default) limit when storms may happen.
Vault Configuration
Vaults are Siptah's primary endgame activity. Each vault spawn is persistent and can be locked by a clan. Vault refresh is set by two shipped keys, VaultRefreshTime=10 and VaultRefreshDeviation=2. Keys that circulate for this, such as VaultRespawnTime or MaxSimultaneousVaults, are not settings the server knows.
Performance Warning: During a maximum-intensity Surge, the server spawns up to 200 AI entities simultaneously. For servers with 20+ players, we strongly recommend dedicated hardware with 16 GB RAM minimum and a CPU with strong single-thread performance.
