How to Get Vile Acceleration in Warframe (2026): Where It Drops, Stats and Is It Worth It

Vile Acceleration increases fire rate by 90% for rifles and 180% for bows, but decreases damage by 15%

Last Updated on September 18, 2026

The short answer

Vile Acceleration is a rare rifle (primary) mod: Vile Acceleration increases fire rate by 90% for rifles and 180% for bows, but decreases damage by 15%. The Orokin Vaults on Deimos: bring all four Dragon Keys, open the vault, and it is about a 4 percent roll per run, so budget ten to twenty runs or pay a few platinum on warframe.market. The bow fire-rate mod: 180 percent on bows for a 15 percent damage cut is the best trade in the game.
