Basic Information[]
The Mob Spawner (also called Creature Spawner) is a machine that can spawn Creatures when switched on by any kind of activation device, which requires wiring.
To open the settings window of the Mob Spawner and select a Creature type that you'd like to spawn, you'll need do have a Wiring Tool equipped and type "n" (as the default key).
Please note that the Mob Spawner has not been created as a means for you to collect tons of loot, so this is not how it works.
The Mob Spawner is an item mainly intended to create game content for other players, for example within Adventures.
For this purpose Creatures that can be spawned will not drop any loot when being killed - except for stuff that you yourself can provide for the first Creature that will spawn (by placing it into the storage window of the mob spawner that can be opened with right click or "f" as the default key).
If you enable the option "requires loot", no Creature will spawn at all as long as you won't put any items into the storage window of the Mob Spawner.
Since update R52 on February 14th 2018, all Ghost Creatures, Night Hoglets, Night Twiggies, blue Keepas, Silver Keepas and Golden Keepas can also be spawned with a Mob Spawner. Keepas and Ghost Creatures will always be flight animals even if the Mob Spawner option "aggressive" is enabled.
Since update R57 on October 24th 2018 at the beginning of the Halloween event 2018 "The Great Pumpkiru Returns", all Halloween-related red ghostly Event Creatures can be spawned with a Mob Spawner too and will always be aggressive, even on game worlds with the "Pro" world option "Passive Creatures" enabled.
Bug warning[]
Since December 2017, Mob Spawners cannot be "hidden" sideways behind a wall nor below floors any longer, since the Creatures will spawn on the very same block as the Mob Spawner, except for Creatures that are 2 blocks in height.
When creating Adventures with the intend that other players should fight the Creatures you spawn, then they will not be able to do so through walls or floors. Sadly, some older Adventures have bugged out because of this.
How to obtain[]
You can craft these machines yourself in your Crafting Menu (to be opened with "q" as the default key) after unlocking the according crafting recipe for free.
30 Mob Spawners can also be bought as part of the Ultimate Machines Pack in the Store, and 5 Mob Spawners are included in the smaller Machines Pack, both are item packs that you can buy multiple times, they don't have any crafting recipes inside. However, claiming both LEDs and Pressure Plates from these Item Packs will unlock the free crafting recipe of Mob Spawners.
Mob Spawners can optionally be bought as parts of (customizable) building kits for any customizable Blueprint with Coins, which in return are purchasable for real money via Steam Wallet in the ingame Store. You can use Blueprints that you have captured yourself with Capture Blocks, as well as Blueprints that were made by other players and that you have subscribed to in the Steam Creativerse workshop, or Blueprints that you have customized with Mob Spawners.
To buy a building kit, either select the according Blueprint or activate a cornerstone that has been placed into the game world (and has optionally been customized). Check the content of the block kit first by clicking on the description "Built with xxx Blocks" before you'll click on the green price tag button below "Get kit and build now".
Mob Spawners can not be obtained from any randomly spawning Treasure Chest nor Creature.
How to unlock the crafting recipe[]
You can craft Mob Spawners in your crafting menu ("q" as the default key) after unlocking the according crafting recipe by:
- crafting or obtaining an LED (a light cube that can be set to a large number of colors) after crafting a Wood Burning Lamp, Wiring Tool and Switch, plus
- crafting or obtaining a Pressure Plate
How to craft[]
One Mob Spawner can be crafted in your crafting menu with:
- 5 Arcstones that can mainly be obtained from Keepas of any kind, either by killing and looting them or by taming, feeding and harvesting from them
- 2 Iron Slabs, created by putting Iron Bars into a Processor
- and 3 Bones that can either be obtained from nearly any Creature by killing or pet-harvesting, or alternatively from blocks of Fossils put into a Processor
Crafting Mob Spawners is the unlocking requirement for the crafting recipes of Loot Spawners.
How to use[]
Mob Spawners will only work after being placed into the game world and wired to at least one activation device like a Sensor, Switch, Number Pad or Pressure Plate with the use of a Wiring Tool. Mob Spawners cannot be switched on by directly activating them.
The Wiring Tool is also necessary in order to access the settings window and select the type of Creature you want to spawn. Each Mob Spawner can only spawn one specific type of Creature when the Mob Spawner is activated. Defensive Creatures can be set to aggressive, which also applies to Creatures that are automatically set to defensive on game worlds with the "Pro" world option "Passive Creatures" ("peaceful Creatures") enabled.
Creatures spawned by the Mob Spawner are supposed to appear over the Mob Spawner (or in front of Spawner if you rotate it sideways, or below, if you ) at the nearest possible free space.
Currently, a bug recognizes the space that the Mob Spawner itself occupies as being "free". So Creatures that are only 1 block in height will spawn directly on (or rather "in") the Mob Spawner, but Creatures that are 2 blocks in height or larger will spawn on any free space nearby. Unfortunately, this will not necessarily be the next free space above the Mob Spawner (or in front of the Mob Spawner, if you rotated this machine).
Mob Spawners placed upside down (on/behind ceilings) do not work properly either, since mobs will be displaced to a free space nearby, not necessarily below (like it has properly worked before the bug), so it's better to avoid placing Mob Spawners on ceilings.
Creatures spawned by Mob Spawners cannot be tamed and will not drop any usual Loot Bags with typical animal materials like "naturally" appearing Creatures would. If Creatures that appear on Mob Spawners should drop loot, it's either the loot from the storage window of the Mob Spawner, or a bug has hit that will most likely be fixed very soon (like it once happened with all types of Keepa shortly after they were freshly added to the Mob Spawner menu).
Loot[]
As said, Creatures that are spawned by a Mob Spawner will not drop any loot, except if players provide loot for the first Creature that will spawn by placing this loot into the storage window of the Mob Spawner.
Mob Spawners cannot simply be "activated" by right-clicking them (or pressing "f" as the default key) like any kind of Door, Lamp, Pet or storage container would.
Instead, by right-clicking on a placed Mob Spawner (or typing "f" as the default key to activate it) that you own or have the permission to use, the storage window will open that you can then fill with loot for the first Mob that you want to spawn.
The storage window of Mob Spawners provides 20 free slots (for 20 stacks of items).
This loot can be anything that you can carry in your inventory, including liquids and items that could not be placed into the game world, like animal materials, armor or potions for example.
The first Creature that will spawn when the Mob Spawner is activated, will drop all of this loot that you have provided in a Loot Bag as soon as the Creature is killed. It will also drop this loot if it's a light-sensitive Creature and burns to nothingness by itself when being "hit" by sunlight.
The loot cannot be split into many storage containers and cannot be split in order to be provided to more than one spawning Creature. Only one - the first - Creature will drop all the loot. All other Creatures spawned afterwards will not drop any loot at all.
If you enable the setting "requires loot", then only one Creature will spawn if loot is in the storage window, and no other Creatures will spawn afterwards.
The storage window also allows you to set permissions so that only players with a certain permission rank on the according player claim or otherwise on the game world will have access to the storage window of the Mob Spawner. For this, click the padlock icon at the top right corner directly over the storage window.
Only players with the permission rank that you define (or an even higher permisson rank) can access this storage window. Claim settings override world settings, but world owners and world mods can open all storage containers even on player claims of other players as long as they can access them. The default setting of the Mob Spawner is "builders", like for all storage containers, machines and activatable objects.
By hovering your mouse cursor over the magnifier icon, you can view the transfer history with the latest accesses to the Mob Spawner storage window - up to the last 5 filling and 5 removal actions with the according player names and time of their access will be displayed.
Changing the settings[]
The settings of the Mob Spawner can be only defined by using an equipped Wiring Tool and typing "n" (default key) while looking at the Mob Spawner. Then the inspection window will open and will let you:
- select the exact type of Creature that you want to spawn,
- define if the Creature should be peaceful or aggressive (with a lot of exceptions, see below)
- and decide if you only want the Creature/s to spawn after providing them with loot (or not)
By clicking the padlock icon in the top right corner, you can define the minimum permission rank for players that they'll need to have on the according claim or game world in order to change the settings of the Mob Spawner (with a Wiring Tool) or even to take this device away.
There's also an option to rename the Mob Spawner (30 characters max.).
Selecting a type of Creature to spawn[]
The list of Creatures that Mob Spawners are able to spawn can be accessed by clicking on the small icon of the Creature shown in the inspection window (to be opened by pressing "n" while having an Wiring Tool equipped and looking at the Mob Spawner in the game world with the cursor). As said, each Mob Spawner can only spawn one type of Creatures, not several different Creatures one after another or "random" Creatures.
Mob Spawners can usually spawn:
- Arctic Mirus (aggressive except on "peaceful" "Pro" game worlds, sunlight-sensitive)
- Autumn Leafies (peaceful, but can be set to "aggressive" with the Mob Spawner). The specific skin color of the Autumn Leafi/s that will be spawned is chosen randomly

- Wraithworms (always aggressive, even on "peaceful" "Pro" game worlds)
- W'urm the Infernal (always aggressive, even on "peaceful" "Pro" game worlds)
A Mob Spawner is not able to spawn Rockzillas. If you want to spawn Rockzillas, you will have to build the according "altars" in the game world from specific blocks and luminaires that will make Rockzillas appear during day time as soon as players get close enough. Rockzillas will be peaceful on "Pro" game worlds that have "peaceful Creatures" enabled, otherwise these large crabs will be aggressive by default.
Mob Spawners can spawn event Creatures, but not all of the Christmas-specific Creatures like Coolworm Minions or Troggington. Formerly, Toy Drive Targets could be spawned for ca. one month around Christmas 2017 and New Year 2017/2018, but these Targets have been removed from the Mob Spawners in January 2018.
Setting Creatures to "aggressive"[]
Since update R39, even peaceful Creatures can be set to be aggressive when spawned by a Mob Spawner, even on game worlds with the "Pro" world option "peaceful creatures" ("Passive Creatures") enabled.
Exceptions are all Ghost Creatures (that usually spawn "naturally" only during the Halloween event-month), all Keepas (including Silver Keepas and Golden Keepas) as well as common green Leafies - these Creatures will always be peaceful and some will even run away from players like they usually do when players approach these fearful Creatures.
Please mind that on the other hand aggressive Creatures cannot be set to be "peaceful"!
However, most aggressive Creatures will automatically be peaceful when spawned by Mob Spawners on worlds where the "Passive Creatures" options is enabled (one of the game world options only available to players who have bought the Pro DLC for Creativerse), of course only as long as the option "Aggressive" is disabled on the Mob Spawner.
All the red ghostly Halloween Creatures (Clarice the Eternal BossHog, Eidoleafi, Ghostevil, Ghostzilla, Hauntster, Mirghoul, Polturpigsy, Poultrygeist, Th'ang the Unyielding, W'urm the Infernal and Wraithworm) will always be aggressive though when spawned by a Mob Spawner, even on game worlds with "Passive Creatures" enabled.
Kindly note that all the Creatures that spawn on a Mob Spawner will otherwise show their typical behaviour, will have their usual weaknesses, strength and toughness depending on the combat difficulty settings of the world (medium = "normal" by default). If you set the "Pro" world option combat difficulty to "easy", Creatures will only deal half the damage as normal, since their damage points are cut in half. If the combat difficulty is "hard", Creatures will hit twice as hard as normally, since their damage points are doubled.
This means that aggressive Creatures will attack your player character when you're close enough, no matter if you were the one who placed the Mob Spawner or just the one who made them spawn.
You can still make aggressive Creatures spawn around your base like watch-dogs, as long as you know a safe way into your base or you can disable the Mob Spawner temporarily with devices like Number Pads (for example) that you wired the Mob Spawner to.
Health bars, combat abilities or damage dealt by spawned Creatures cannot be increased or decreased by using the Mob Spawner, so be aware of spawning tough monsters (like corrupted ones or always-aggressive Event Creatures) or be prepared for a fight.
Night Creatures and some Underground Creatures spawned by a Mob Spawner will burn away in the sun like they usually do; with the only difference that they CAN leave Loot Bags behind
Of course, they can only drop a Loot Bag if loot has been in the storage window of the Mob Spawner and of course the Loot Bag will then only be filled with the loot that players have provided them with via Mob Spawner.
If the owner of the Mob Spawner does not place any items into the inventory window of the Mob Spawner, none of the Creatures that spawn will drop any loot, no matter in which ways they are killed.
Again, please note that only the first Creature that spawns and dies will drop all the loot that you has been placed into the inventory window of the Mob Spawner. All the following Creatures that the Mob Spawner will spawn if you do the option "requires loot" is disabled, will not drop any loot.
"Requires loot"[]
This option will make sure that only one - the first - Creature will spawn that will carry all the loot from the storage window of the Mob Spawner and will drop it as a reward for players that can kill this one Creature. As long as no loot is placed in the storage window, the Mob Spawner will spawn no Creatures at all.
This option is intended to make the spawning Creature drop specific loot for players who manage to kill it, mainly in Adventures. This loot can be equipment that player characters can wear during the Adventure, or items that can be placed into Teleporters as codes for example. It can alternatively be a reward for players that visit your base (usually only after you've invited them) and are able to kill the spawning Creature.
If you want to reward players this way, you will have to put the loot into the according storage window by right-clicking the Mob Spawner after placing it, or typing "f" as the default key.
By doing this you can "fill" only the first Creature that will spawn with all kinds of items (including crafted items, food, liquids, potions, etc.) that the Creature will then drop when being killed by a player - in order to provide a challenge and then a reward for other players. Please note that sunlight sensitive Creatures will die by themselves if hit by sunlight, and will then also drop the Loot Bag just as if they've been killed by players. The same goes for Creatures that die by drowning, by being burnt or poisoned to death, or by freezing to death. Creatures do not suffer any fall damage.
If you enable the optional setting "requires loot" in the inspection window of the Mob Spawner (opened by typing "n" as the default key, with a Wiring Tool in hand while pointing the cursor at the Mob Spawner), only one Creature will spawn after you've put some stuff into the storage window, this Creature will then drop all the stuff that you've provided when killed, and no more Creatures will be spawned by this Mob Spawner.
If you keep the option "requires loot" disabled (by default), only the first Creature will drop items if you have optionally put some into the inventory window of the Mob Spawner. Still, more Creatures can now be spawned that won't drop any loot - one more of them every time the Mob Spawner is activated (for example by a Sensor, a Pressure Plate, a Switch or a Number Pad).
You cannot split the loot to make more than one Creature drop it, and you cannot multiply loot this way.
Permission settings[]
When opening the inspection window (opened by typing "n" as the default key, with an Wiring Tool in hand while pointing the cursor at the Mob Spawner) or the storage window for the Mob Spawner (to be opened with right click or "f" as the default key), you can change permission settings (access control).
To change permission ranks for access to the Mob Spawner, click on the padlock symbol in the top right corner just above the inspection window or storage window, in order to either allow or prevent other players of certain permission levels to change the settings of the Loot Spawner or to even take it.
Available world permission-settings: "just me", "world owner/admins", "world mods", "builders" or "everyone". On player claims the available settings are "just me", "claim admins", "claim interact only", "claim builders" and "everyone".
Mob Spawner are set to "builders" (and "claim builders" when on player claims) by default when being placed. So players with at least builder rights (permission rank) or higher either on your game world or on your claim (claim permission ranks override world permission ranks) can access your Mob Spawners.
You can set the permission to "just me" if you want to, so your Mob Spawner settings will only be accessable by you - and players with higher ranks than you might have yourself on the respective player claim or game world. These same players could theoretically even pick up and take the Mob Spawner for themselves.
If the permission setting is set to "visitor", everyone can access the Mob Spawner and could even take it away. Only on player claims, a special permission rank "claim interacts only" will allow players with this permission rank to access your Mob Spawners, but not to take them away.
Renaming the machine[]
Mob Spawners are wireable machines that can also be renamed (up to 30 characters) by clicking on the square icon with a "pen" in the top right corner above the inspection window or also in the storage window of the Mob Spawner.
Transfer history[]
Only when opening the storage/inventory window of the Mob Spawner, you can move your mouse cursor over the magnifying glass icon in the top right corner next to the note+pen symbol and padlock symbol to then view a "Transfer History" that lists the last 5 filling and 5 removal actions with the according player names and time of their access to the Mob Spawner.
Special Creature types[]
During event-times like Halloween (like for Pumpkiru's Candy Campaign 2017) or Christmas (like for Elfi's Toy Drive 2017-2018), some Event Creatures were only temporarily added to the Mob Spawner and then removed after the events were over.
It is possible that Mob Spawners will allow to spawn Christmas-related Creatures like Coolworm Minions or Troggington during the according event-times, but will not continue to spawn them after the event time has ended. The Mob Spawner menu will be set back to its default Creature list, so it will not let you select these types of Creatures to spawn any longer after you've de-selected them. However, a bug has been known in 2018 that has caused Mob Spawners to continue spawning specific Event Creatures even though they had been removed from the Creature selection list.
