The expiration rate of a temporary effect describes how fast or slow time progresses for that effect relative to real time.
Ordinarily, the expiration rate of a temporary effect is equivalent to real time – that is, one second of temporary effect duration lasts one actual second – however, there are modifiers that can increase or decrease it. Modifiers that cause a temporary effect to expire x% slower decrease the expiration rate of that effect, thereby making it last longer. Similarly, modifiers that cause it to expire x% more quickly (or expire x% faster) increase its expiration rate, making it last a shorter period of time.
Mechanics
Despite changing the total time that temporary effects last, it does not increase or decrease the duration of that temporary effect. For most characters this difference does not matter, because the main goal is an overall longer or shorter time for the game mechanic. The difference only matters for benefits and/or downsides that only affect expiration rate or duration. For example:
- Vaal skills with duration buffs/auras, like Vaal Molten ShellVaal Molten ShellSpell, AoE, Duration, Fire, Physical, Vaal, Guard
Level: (1-20)
Cooldown Time: 0.50 sec
Can Store 1 Use(s)
Souls Per Use: 50
Can Store 1 Use(s)
Soul Gain Prevention: 14 sec
Cast Time: InstantRequires Level 4Applies a buff that raises your armour, and takes some of the damage from hits for you before being depleted. Each second, the skill deals reflected damage to surrounding enemies based on the damage taken by the buff in that second. When the buff is removed, the skill deals reflected damage to enemies around you based on the total damage that was taken by the buff. You cannot have the buff at the same time as any other Guard skill.Base duration is 9.00 seconds
Modifiers to Skill Effect Duration also apply to this Skill's Soul Gain Prevention
Buff grants +(50-858) to Armour
(35-39)% of Damage from Hits is taken from the Buff before your Life or Energy Shield
Buff can take Damage equal to 20% of your Armour, up to a maximum of 10000
Reflects (300-9000)% of Damage taken from Buff as Fire Damage each second,
or when Buff expires or is depleted

Therefore having these skills expire slower on you will result in them being active more often than increased duration would.
Temporary effects that can possibly be affected by expiration rate include buffs, debuffs, curses, flask effects, and temporary auras. Temporary effects that are not affected by expiration rate include rage and Focus, which don't have a modifiable duration, but instead apply at fixed rates or for fixed intervals.
Slower expiry rate is capped at 75% after combining all sources, or a 4x effective duration.[1]
Formulas
The modifier expire x% faster has diminishing returns, while the modifier expire x% slower has increasing returns.
Expiration Rate
The expiration rate of an effect, where IncreasedExpirationRate and DecreasedExpirationRate are the sums of all expire #% faster and expire #% slower modifiers applicable.
Effective Duration
From its base duration and expiration rate, we can calculate the effective duration of an effect.
Sources of expiration rate
Gems
- Temporal ChainsTemporal ChainsSpell, AoE, Duration, Curse, Hex

+(0-1) metre to radius
50% less Effect of Curse against Players
Cursed Normal and Magic Enemies have (15-29)% less Action Speed
Other effects on Cursed enemies expire 25% slower
Cursed Rare and Unique Enemies have (9-18)% less Action Speed
