Abyssal filaments
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 seven 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 seven levels of the abyss which dictate the strength of the penalty are outlined in this table below:
| Level | Name | Appearance | Penalty Strength |
|---|---|---|---|
| 0 | Tranquil |  |
-30% or -50%, random per site |
| 1 | Calm | 
| |
| 2 | Agitated | 
| |
| 3 | Fierce | 
| |
| 4 | Raging |  |
-50% or -70%, random per site |
| 5 | Chaotic | 
| |
| 6 | Cataclysmic | 
|
The bonus and penalty effects found in each of the five weathers are as follows:
| Weather | Penalty | Bonus |
|---|---|---|
| Electrical |  -30/50/70% EM Resist |
 -50% Capacitor Recharge Time
|
| Dark |  -30/50/70% Turret Optimal and Falloff Range |
