Triglavian Invasion (Chapter 1 & 2)
Triglavian Invasion (Chapter 3)

Abyssal Deadspace is an area of isolated space. It was added to the game in the Into The Abyss expansion that went live on May 29th 2018. It was further expanded in the Onslaught expansion that was released on the 13th November 2018, and again in the Depths of the Abyss update on the 15th September 2020.

It is accessible only with the use of filaments and even then only limited pockets are accessible for a limited time. The abyssal deadspace is filled with dangerous localized space effects and any ship that ventures away from the stable pocket or stays in for too long will be destroyed by these effects.

Site Basics

Tier 1 filament: The info of the filament shows what the properties of the site it opens are. That it is a tier 1 filament can be seen by the 1 glowing stripe on the icon.
Triglavian Bioadaptive Cache contains the loot for each pocket.
Triglavian Extraction Node also contains the loot for each pocket.

A new type of space can be accessed using filaments obtained from data sites and from abyssal deadspace. Seven tiers of increasing difficulty exists. The Abyss is limited to either:

  • A single Tech I, Tech II, Navy Faction or Pirate Faction cruiser
  • Up to two destroyers
  • or up to three frigates

and is accessed by activating a filament in space. When activated, a combat-probable beacon (named Abyssal trace) is created at your entry location that allows others to await your return from the pocket.

Activation can be anywhere in space, as long as the following conditions are satisfied:

  • No Gates, Stations or mobile depots at less than 1000 km.
  • No other Abyssal trace at less than 1000 km.

An Abyssal Deadspace instance is composed of three pockets. Each pocket must be cleared of enemies for a gate to open to the next pocket. In addition to Triglavians, you may find rogue drones under their command. Drifters (without doomsday and rarely with overshield) may appear as well, accompanied by sleeper drones, engaged in combat with the Triglavians. However, no one will help you. You must fight your way out.

Within the Abyss, in each pocket is a structure called the "Triglavian Bioadaptive Cache" which has a scant 300 hit points and contains some of the loot for that pocket. There are also "Triglavian Extraction Nodes" and "Triglavian Extraction SubNodes" which also contain additional loot.

Extraction nodes and subnodes do not appear in Tier 0 Abyssal Deadspace.

The deadspace instance is stable for only 20 minutes. If you are still in the pocket after 20 minutes your ship and your pod will be immediately destroyed. Essentially, you must clear the three pockets and exit with the allocated time, or you will lose both your ship and your pod. The third pocket gate returns you to the location in space you activated the filament from.

Further site restrictions: you can not be warped to within the Abyss, nor can you warp out of it. You can not cloak nor deploy a mobile depot. There is no local. Core Probes and Combat probes launched will be removed from space shortly after launching and cannot be recovered. The Directional Scanner will not work. The map does not work. At the present moment, if a player is in Abyssal Deadspace when server downtime occurs, the player will return to the solar system they entered from.

Quick recap:

  • There are 7 tiers of Abyssal Deadspace combat sites.
  • There are 5 different types of weather effects in the sites, each with their own site bonus and weakness.
  • The NPCs you face inside the Abyssal Deadspace are random.
  • Once you enter an Abyssal Deadspace, a 20 minute timer begins. If the site is not completed within that time limit, you lose your ship and pod.
  • Loot is found in Triglavian Bioadaptive Cache (main loot for cruiser sites), Triglavian Biocombinative Cache (main loot for frigate sites), and Triglavian Extraction Nodes and SubNodes. NPCs leave no wrecks to loot or salvage, although cache wrecks can be salvaged for Triglavian materials.
  • With the Onslaught expansion, a player-versus-player element was added to Abyssal Deadspace, accessed optionally through a second exit gate (named Triglavian Proving Conduit) in the final room of Tier 3 sites and higher.
  • The Onslaught expansion also released 3 player co-op frigate Abyssal Deadspace pockets.
  • Note that the Triglavian Proving Conduit has been removed due to the addition of Proving Filaments in the Depths of the Abyss expansion. These filaments will transport a player directly to the Proving Grounds without the need to go through Abyssal Deadspace.
Three types of gates you will encounter are: Triglavian Origin Conduit, Triglavian Transfer Conduit, and Triglavian Proving Conduit. A gate with a triangle in the center means you still have more pockets to go!
Icon warning.png WARNING: Any ship and capsule should be considered lost the moment a player enters Abyssal Deadspace. The atmosphere is rather unforgiving to inexperienced, ill-equipped or unfamiliar pilots. If your ship is lost inside the site, you will lose your capsule, clone, and implants (if equipped) as well. Do not run Abyssal Deadspace complexes with a ship or with implants that you cannot afford to lose.

Enviromental Effects

Abyssal deadspace has several enviromental effects that will all apply to both the player ship and to the NPC ships. These effects will neutralize unprepared ships but they can also be taken advantage of. All effects applied to your ship will be shown in same location as EWAR effects. Hover your mouse over the icon to see what effect is applied to your ship.

Weather Effects

Each Abyssal Deadspace instance will have a weather effect that spans over all three pockets of the instance. Five types of environmental weather effects exist affecting both player and NPCs. The type is identified on the info of the filament and can be countered if desired by fitting choices. The name of the filament itself gives clues as to what tier and difficulty it is. A Raging Exotic Filament means that it is a Tier 4 site with Exotic Particle Storm effect. A Fierce Dark Filament is a Tier 3 site with Dark Matter Field effect.

The bonus modifier of the weather is always 50% but the strength of the penalty varies by the level of the instance.

Level Filament Name Filament Appearance Penalty Amount
0 Tranquil AbyssalFilamentL0.png -30% or -50%, random per run
1 Calm AbyssalFilamentL1.png
2 Agitated AbyssalFilamentL2.png
3 Fierce AbyssalFilamentL3.png
4 Raging AbyssalFilamentL4.png -50% or -70%, random per run
5 Chaotic AbyssalFilamentL5.png
6 Cataclysmic AbyssalFilamentL6.png

The level of the filament can also be identified by the number of glowing stripes on the icon.

The five Abyss-wide environmental effects are outlined in this table below:

Weather Type Penalty Type (strength defined by level above) Bonus Provided
Electrical Icon resist em.png Penalty to EM Resist Icon capacitor capacity.png Bonus to Capacitor Recharge Time (-50% charge time and therefore +100% charge rate)
Dark Icon target range.png Penalty to Turret Optimal and Falloff Range Icon velocity.png Bonus to maximum velocity (+50%)
Exotic Icon resist kin.png Penalty to Kinetic Resist Icon sensor resolution.png Bonus to Scan Resolution (+50%)
Firestorm Icon resist therm.png Penalty to Thermal Resist Icon armor.png Bonus to Armor HP (+50%)
Gamma Icon resist exp.png Penalty to Explosive Resist Icon shield.png Bonus to Shield HP (+50%)

When selecting ship you must consider the weather effect of the instance you are entering. For example using a turret ship or drone boat in dark matter field (range penalty) is very bad idea as you would likely not be able to hit anything.

The weather bonuses and penalties apply to all entities within the abyssal deadspace. This includes your ship, rats, missiles and drones. The environmental effects are stacking penalized.

As the resist penalty will apply to the rats too you should pick your damage type to match the resist weakness. How negative resist bonus is applied to a ship may seem confusing. The easiest way to think of it is that a -50% resist penalty means the ship will take 50% more damage. For more in depth explanation see negative resists on tanking page.

Localized Effects

Filament Cloud (orange) and Bioluminescence Clouds (blue)
Deviant Automata Suppressor

The pockets will also contain clouds and Triglavian towers that will apply effects to player and NPC ships in their immediate vicinity.

Localized Clouds:

  • Filament Cloud (orange): Penalty to Shield Booster boosting (-40%) and reduction to shield booster duration (-40%). If using a conventional (not Ancillary) shield booster, in effect this does not weaken your shield booster, it increases its capacitor cost/second by 66%. If you rely on a shield booster to survive, you should avoid entering these.
  • Bioluminescence Cloud (light blue): +300% Signature Radius (4.0x signature radius multiplier). Entering this cloud will make your ship easier target to hit but it will also make all rats easier to hit. If fighting small but accurate enemies like Damaviks, this cloud can actually be helpful to pull enemies through.
  • Tachyon Cloud (white): +300% Velocity (x4.0 velocity), -50% Inertia Modifier. Be very careful entering this cloud with an active MWD, as the Inertia reduction will cause you to accelerate very quickly (x4 velocity, x0.5 inertia, x8 acceleration), potentially slingshotting you outside the boundary for a very quick death to the Unstable Abyssal Depths. These clouds will also increase enemy velocities, causing them to either close range very quickly, or suddenly pull away.

Triglavian Towers:

  • Deviant Automata Suppressor: Damages all missiles, drones, and rogue drone frigates within it area of effect. The larger does about the same damage to drones as a single medium smartbomb; the smaller does more than double that. Flying into the range of this Suppressor can help you take out pirate drones.
    • Short-Range Deviant Suppressor will attack all drones, missiles and rogue drone frigates within 15 KM
    • Medium-Range Deviant Suppressor will attack all drones, missiles, and rogue drone frigates within 40 KM
  • Multibody Tracking Pylon: +60% or +80% tracking to all ships in its area of effect.

Rat info

The Abyssal Deadspace contains variety of different kind of rats. Each rat will behave differently and taking the right approach in different situations is important. For a quick overview of which group of rats you can face go to the Possible rooms in Abyssal Deadspace page.

Rogue Drones

Rogue Drones are perhaps the most common type of rats encountered in Abyssal Deadspace. The sub battleship rats deal single damage type or EWAR based on their name. The battlecruiser-sized rats are notable for having very high damage combined with very short range and incredible tracking, they will easily be able to track and hit medium drones that are attacking them. If you can keep them at over 10 km from your ship they will deal very little damage.

The best strategy is to start out by killing EWAR rats that pose threat to your ship. Depending on your fit, this means webs, tracking/missile disruptors and, if the pocket has battleships, target painters. You should also pay attention on whether logistic rats are on grid. If you can't kill other frigates before repairs land, prioritize killing logistic rats first. After the dangerous EWAR and logistic rats are dead you can focus on the damage dealers in your preferred order.

The rogue drone frigates are susceptible to automata suppressors. Multibody tracking pylons and bioluminescent clouds will also help greatly when trying to hit small frigate swarms.

The Rogue Drone battleship found in Tier 5 sites, known as the Benthic Abyssal Overmind has a stasis webifier, making it difficult to maneuver around this enemy.

Drifters and Seekers

Drifters and seekers are sometimes encountered together but they can appear on their own too. They all deal omni-damage types and have flat omni-resist profiles.

Drifter ships most often start with damaged shields and armor. The battleship deals heavy damage but a cruiser can get under its guns to avoid taking hits. The battleship will also fly away from the player ship at a speed of around 300m/second and will try to drag the player to the boundary. The drifter cruisers all use some form of EWAR in addition to dealing damage.

Sleeper Drones

Every Sleeper drone is equipped with remote repairers so it is best to kill smaller ships first as they die before repairs land. In addition to damage, they will also use webs and energy neutralizer. The Sleeper drone battleship(Lucid Deepwatcher) deals rather high omni damage but cannot hit ships if they are around 10 km from it.

Triglavian Collective

Triglavian ships can appear in any pocket and regardless of size will have remote armor repair capability along side their unique Entropic Disintegrator weapon system. Their weapons deal Explosive and Thermal damage, and their dps can be very high. They will also use drones as supplemental weapon system. Many Triglavian ships will also use remote repairs.

Sansha's Nation

All Sansha's Nation rats have the Devoted prefix. They have VERY good tracking and can start applying damage to you even if you have just landed in the pocket.

All CONCORD rats are part of the Disparu Troop. CONCORD hulls use missiles, while EDENCOM ships use Vorton Projectors. The EDENCOM ships' AI can be exploited to bounce Vorton Projector damage to other CONCORD/EDENCOM ships; the chain will affect ANYTHING NEARBY, including caches, extraction nodes, drones and other enemy ships.

CONCORD rats are generally feared by many Abyssal runners due to their high missile damage and heavy EWAR. The sheer incoming DPS makes passive tanking these rooms extremely difficult. Because of this, Marshal rats (especially Drainers which neut your cap very hard) are often targeted first to reduce incoming DPS.

Best damage to deal

The Abyssal Deadspace resist penalties apply to both the player ship and to the rats inside Abyssal Deadspace. Due to how resist penalties are calculated this means that damage matching with the penalized resist will effectively receive damage bonus equal to the resist penalty (smaller damage increase if the target has too low resist). So in general you should select your damage to match the weather. But sometimes the natural resist hole of the rat is equal or even greater than the resist hole caused by the weather. In level 1-3 electric storm pockets the weather induced resist hole is equal to explosive resist hole. In all other pockets the weather induced weakness is greater.

Drifter ships, seeker drones and sleepers have uniform resists.

Icon damage em.png EM Icon damage kin.png Kinetic Icon damage therm.png Thermal Icon damage exp.png Explosive

The rogue drone ships have wildy varying resists. Generally the weather induced weakness is the greatest resist hole to hit. Hitting natural resist hole of the battleship drone deals approximately 10%-20% more damage than not hitting any weakness. Rogue drone battleship weaknesses are:

Abyssal Deadspace Co-op for frigate fleets

Co-op frigate Abyssal Deadspace can be run by a group of up to 3 T1/T2/faction frigates. This requires three of the appropriate filaments of the same type the fleet desires to run, which all need to be in a single ship's cargo hold. The pilot can then activate a fleet abyssal site by right clicking on the stack of filaments selecting and then selecting "Activate For Fleet" in the window that pops up. Once activated an acceleration gate will appear in space and each member of the fleet (up to three T1/T2/faction frigates) can each activate the gate and enter the deadspace pocket to run the sites as described above.

Abyssal Deadspace from the outside

As of August 14th, 2018, the suspect timer given upon exiting T4 and T5 Abyssal Deadspace has been "temporarily" removed.
Orange glow means it is a tier 1-3 Abyssal Deadspace. Yellow glow means it is a tier 4 or 5 Abyssal Deadspace.

When you enter the Abyssal Deadspace, you will be removed from local and from directional scanner. You cannot see who is in the system outside the deadspace, and they cannot see who is inside or in what ship. But that does not mean you are safe. Once the filament has been used, a rift appears that can be combat scanned by anyone in the system and can be warped to. It also appears on the directional scanner of anyone who has not filtered it out. This makes it easy for people to camp the exit and shoot whoever comes out.

This means that you have to consider where you use the filament, especially in low security and null security space. But even in high-security space you are not safe. It used to be the case that Tier 4 and 5 filaments would give you suspect timer, but that has been "temporarily" disabled as of August 14th, 2018.

You will be invulnerable for a short time, so be patient if you leave the rift and find yourself being camped. A survival tactic could be to quickly activate a new filament - especially a tier 1-3 filament that you run in order to run down a suspect timer in hisec - but beware, many players have now got wise to this and will anchor a mobile depot which will prevent you activating another filament.


Abyssal Deadspace is dangerous, but the rewards can be worthwhile for those who can complete the sites. Abyssal Deadspace is the only source for many valuable items, which are found in the Caches and Extraction Nodes/SubNodes. No wrecks are left behind by any NPCs, all drops come from these two listed cans. Rewards are as follows:

  • Mutaplasmids that can be used to change the stats of certain modules. Which mutaplasmids are able to drop depends on the weather selected:
    • Gamma sites can drop shield related mutaplasmids - S/M/L Shield Extender, S/M/L/XL Shield Booster
    • Dark sites can drop propulsion module mutaplasmids - 1/10/100MN Afterburner, 5/50/500MN Microwarpdrive
    • Firestorm sites can drop armor related mutaplasmids - S/M/L Armor Plate, S/M/L Armor Repairer
    • Electrical sites can drop capacitor related mutaplasmids - S/M/L Cap Battery, S/M/L Energy Neutralizer, S/M/L Energy Nosferatu
    • Exotic sites can drop tackle related mutaplasmids - Stasis Webifier, Warp Disruptor, Warp Scrambler
    • All weathers can drop damage module mutaplasmids - Heat Sink, Gyrostabilizer, Magnetic Field Stabilizer, Ballistic Control System, Entropic Radiation Sink
    • T6 filaments can drop capital module mutaplasmids - All Capital-sized versions of the modules above, plus Ancillary Shield Booster/Armor Repairer, Heavy Warp Disruptor/Scrambler, and Siege Module
  • Precursor ship and weapon skill books, disintegrator specialization skill books
  • Blueprint copies required for the production of Triglavian hulls, weapon systems, and ammunition:
    • Triglavian ship hulls
    • Entropic Disintegrators: Weapons with unique properties and only usable by the Triglavian ships
    • Exotic Plasma: Ammunition used by Entropic Disintegrators
    • Mutadaptive Remote Armor Repairer: A special remote armor repairer module used by the Triglavian Rodiva and Zarmazd logistics cruisers
  • Production materials required for the production of Triglavian hulls, weapon systems, and ammunition:
    • Crystalline Isogen-10
    • Zero-Point Condensate
  • Modules:
    • Compact Entropic Radiation Sink - a compact (low-fitting) version of the Entropic Radiation Sink
    • Perun Heavy Mutadaptive Remote Armor Repairer - a faction version of the Mutadaptive Remote Armor Repairer
  • Triglavian Survey Database: Often referred to as "red loot", this item is an ISK token item similar to Sleeper "blue loot" and Overseer's Personal Effects in that it can be sold to unlimited NPC buy orders for a fixed price, in this case, 100,000 ISK/ea
  • Abyssal Filaments: While data hacking sites are the only source for Abyssal Filaments outside of Abyssal Deadspace, and they only provide Calm (Tier 1) filaments, the Bioadaptive/Biocombinative Cache in Abyssal Deadspace can drop filaments of all tiers, allowing us to access the higher tiers of this content. These filaments can also be sold on the open market to other players.
