Duration is one of the stats in Vampire Survivors. It affects how long certain weapon effects last.
The player has 100% base Duration before modifications. The Duration in the stat panel is given as the difference to the base Duration, meaning that Duration stat of +30% equals to 130% total Duration, for example. Duration modifications from characters, PowerUps and items stack additively. Other modifiers, such as Arcanas, stack multiplicatively with the collective bonus from the aforementioned.
The upper limit of total Duration after character, PowerUp and item modifications is 500%. Bonuses from Arcanas are unaffected by the limit.
Duration also affects:
- Base Damage of
Four Seasons 
, Godai Shuffle and Hydro Storm - Critical Damage of Rune Sword
- Amount of Santa Javelin
