Abyssal filaments

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.

A filament is a kind of "key" that unlocks entry into Abyssal Deadspace. Filaments can be found in some Data Sites and also inside of some abyssal deadspace pockets. Within an abyssal deadspace pocket, there are five possible weather effects that affect both the player and NPCs. There are also five possible difficulty levels, with increasing penalties applied in each tier. The type of weather effect is identified on the info of the filament, as is the tier/difficulty level of the filament. The level of the filament can also be identified by the number of glowing stripes on the icon. The bonus modifier of the weather is always 50% but the strength of the penalty varies by the level of the instance.

The five levels of the abyss which dictate the strength of the penalty are outlined in this table below:

Calm (level 1) -30% penalty

Agitated (level 2) -30% penalty

Fierce (level 3) -30% penalty

Raging (level 4) -50% penalty

Chaotic (level 5) -70% penalty

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

Weather Type	Penalty Type (strength defined by level above)	Bonus Provided
Electrical storm	Penalty to EM Resist	Bonus to Capacitor Recharge Time
Dark matter field	Penalty to Turret Optimal and Falloff Range	Bonus to maximum velocity (+50%)
Exotic particle storm	Penalty to Kinetic Resist	Bonus to Scan Resolution (+50%)
Plasma firestorm	Penalty to Thermal Resist	Bonus to Armor HP (+50%)
Gamma-ray afterglow	Penalty to Explosive Resist	Bonus to Shield HP (+50%)

For example, a Raging Exotic Filament means that it is a Class 4 site with Exotic Particle Storm effect. A Fierce Dark Filament is a Class 3 site with Dark Matter Field effect.
