Some weapons in Warframe scale better from increased attack speed rather than raw damage, especially when sustained firing becomes the main source of overall output in combat.
Vile Acceleration increases fire rate significantly while reducing damage per shot, shifting weapon performance toward faster cycling instead of heavier individual hits.
This makes it a mod that changes weapon pacing entirely, turning slower firing setups into rapid output builds that rely on continuous pressure rather than single shot impact.
How To Get Vile Acceleration?
Vile Acceleration is obtained from Orokin Vaults located in Deimos missions, which require Dragon Keys equipped in your loadout to unlock hidden vault rooms during runs.
After opening a vault, you receive one corrupted mod from a shared pool, meaning the drop is random and not guaranteed to be this specific mod each time.
Farming it usually involves repeated vault clears over multiple missions, since acquisition depends entirely on RNG rather than any fixed or targeted reward source.
Vile Acceleration Effects
Vile Acceleration increases fire rate for rifles and bows, allowing weapons to fire significantly faster and produce more shots over the same time period.
In exchange, it reduces damage per shot, lowering individual hit strength but shifting overall performance toward sustained firing instead of single shot impact.
The fire rate boost is especially effective on automatic rifles where continuous shooting directly increases total DPS through higher projectile output.
On bows, the increased fire rate reduces charge time, making each shot release faster and improving responsiveness during combat.
The damage penalty is additive with other mods, meaning it slightly lowers base output but is usually outweighed by the increased firing frequency in practice.

Rank | Rifle Fire Rate | Bow Fire Rate | Reload Speed | Capacity |
0 | +15% | +30% | -2.5% | 4 |
| 1 | +30% | +60% | -5% | 5 |
2 | +45% | +90% | -7.5% | 6 |
| 3 | +60% | +120% | -10% | 7 |
4 | +75% | +150% | -12.5% | 8 |
| 5 | +90% | +180% | -15% | 9 |
Verdict
Vile Acceleration is most effective on weapons that benefit more from firing faster than dealing high damage per individual shot.
It fits naturally on automatic rifles and bows where increased attack speed directly translates into higher sustained damage output during engagements.
The damage reduction is usually manageable, since the added fire rate often results in noticeably higher overall DPS when the weapon is fully utilized.
