~ In Game Description

In Deep Rock Galactic, certain weapons, weapon mods, grenades, and perks are able to inflict the Fear Status Effect on Glyphid enemies (excluding Brood Nexus), Huuli Hoarders, and Mactera enemies.

Effects on Enemies[edit | edit source]

If the Fear Status Effect gets applied to ground-based enemies like Glyphids or Huuli Hoarders, they should stop what they're doing and attempt to flee from the source of the Fear. Sometimes this is able to interrupt a Praetorian spit attack or Radioactive Praetorian roar attack, but it's not consistent. If an enemy is running away from a source of Fear, they gain a "Flee" movespeed multiplier of x1.5 (with some exceptions, see below) until they have moved 10m away from the source of Fear. Once the Fear Effect has ended, they resume normal behavior.

Similarly, applying the Fear Status Effect to Mactera enemies will cause them to cancel their current attack or move command and fly 10m away from the source of Fear at normal speed before resuming normal behavior. From observation, it appears that Fear isn't able to cancel Mactera Bombers' strafe attacks.

Probability to Inflict Fear[edit | edit source]

For most enemies in the game, the probability to inflict Fear on them is the listed "Fear Factor" percentage. Certain enemies have Fear Resistance, though, which makes it harder to inflict Fear on them. Below is a table of all enemies in DRG that have Fear Resistance, what their Fear Resistance is, and the effective probability that they will have Fear inflicted on them based on various Base Fear Chances. Any values over 100% can be seen as equal to 100% since that would be a guaranteed application of the Fear Status Effect.

Enemy Name Fear Resistance 13% Fear 50% Fear 100% Fear 250% Fear 1000% Fear
Glyphid Acid Spitter 30% 9.1% 35% 70% 175% 700%
Glyphid Web Spitter 30% 9.1% 35% 70% 175% 700%
Glyphid Grunt 50% 6.5% 25% 50% 125% 500%
Glyphid Grunt Guard 50% 6.5% 25% 50% 125% 500%
Glyphid Grunt Slasher 50% 6.5% 25% 50% 125% 500%
Glyphid Praetorian 50% 6.5% 25% 50% 125% 500%
Glyphid Warden 50% 6.5% 25% 50% 125% 500%
Huuli Hoarder 50% 6.5% 25% 50% 125% 500%
Glyphid Menace 70% 3.9% 15% 30% 75% 300%
Glyphid Bulk Detonator 100% 0% 0% 0% 0% 0%
Glyphid Crassus Detonator 100% 0% 0% 0% 0% 0%
Glyphid Dreadnought 100% 0% 0% 0% 0% 0%
Glyphid Oppressor 100% 0% 0% 0% 0% 0%

The probability that any given source of Fear Factor will inflict the Fear Status Effect on any given creature is as follows:

Probability to inflict Fear = Base Fear Chance x (100% - Enemy's Fear Resistance)

Such that if an enemy's Fear Resistance is 100%, they cannot have Fear inflicted (with some exceptions, see below).

Interaction with other Crowd Control Status Effects[edit | edit source]

Once the Fear Effect has been inflicted on an enemy, their only active command is to move 10m away from the source of Fear before they can resume normal behavior. As a result of this, Slowing an enemy either before or during the Fear effect will extend the Fear duration because it takes them longer to reach the goal distance. Similarly, Stunning or Freezing an enemy during the Fear Effect will "pause" the effect because they are unable to move. As a result of this behavior, Stunning, Freezing, or Slowing enemies that have had the Fear Effect applied to them is a very effective form of Crowd Control stacking because it functionally extends the duration of the Fear.

Duration of Fear Status Effect[edit | edit source]

This isn't fully confirmed yet, but from observation it appears that the duration of the Fear Effect is tied to the distance traveled, rather than a set time duration like the Stun Status Effect. From testing, it appears that the goal distance to travel is around 10m. As a result, enemies that have faster Max Movespeeds will reach the goal distance sooner, therefore having a shorter duration of Fear Effect than their slower counterparts. Using this logic, Glyphid Exploders and Swarmers should be Feared for the least amount of time, while Glyphid Praetorians should be Feared for the most amount of time. As mentioned above, slowing enemies either before or during the Fear Effect will increase the time it takes to travel the full distance, and by extension increase the time that the enemies are Feared.

At its core, the duration of the Fear Effect is just how long it takes a particular enemy to traverse the goal distance, which can be expressed as Time = Distance / Speed. Initially, the Speed in the denominator is just the enemy's Max Movespeed, but then we have to account for several movespeed modifiers. As mentioned above, when ground-based enemies have the Fear Effect applied to them, they gain a x1.5 "Flee" movespeed multiplier. In addition, each Hazard Level has a movespeed modifier that applies to all enemies, ranging from 0.8 - 1.1. Finally, if the enemy is slowed by anything (like Neurotoxin's 30% slow, IFG's 75% slow, or Electrocute's 80% slow) the movespeed needs to be multiplied by (1 - Slow) so that the movespeed is reduced appropriately.

Summing it all up:

  • Let T be the duration of the Fear effect, or how long it takes this particular enemy to travel the full 10m distance
  • Let M be the creature's Max Movespeed (terms of m/sec)
  • Let D be the Difficulty Scaling modifier (ranges from 0.8 - 1.1 depending on Hazard Level)
  • Let S be the movement Slow applied to the enemy, ranging from 0 (no slow) to 0.8 (Electrocute DoT Status Effect)

\[ \begin{align} Time &= \frac{Distance}{Speed} \\ \\ T &= \frac{10}{1.5 * M} * \frac{1}{D} * \frac{1}{1.0 - S} \\ \\ T &= \frac{10}{1.5 * M * D * (1.0 - S)} \end{align} \]

Disclaimer: Mactera enemies don't seem to gain the same x1.5 Flee multiplier, nor do they use their Max Movespeed to achieve the goal distance. As such, the above formula should only be used for ground-based enemies, and not for Mactera enemies.

Special Cases[edit | edit source]

Although under normal conditions Glyphid Oppressors, Bulk Detonators, Crassus Detonators, and Dreadnoughts cannot have the Fear Status Effect inflicted upon them since their Fear Resistance is 100%, there are three exceptions:

  • Field Medic revive
  • See You in Hell explosion
  • Bosco revive

All three of those sources of Fear are accompanied by a bright flash of light and ignore the normal Fear Resistance check, causing them to have a 100% chance to inflict Fear on all enemies. When this happens, the "Flee" movespeed multiplier is changed to x2 for Glyphid Oppressors and x1 for Glyphid Bulk Detonators, Crassus Detonators, and Dreadnoughts.
