OSRS Potion Timer

How long every potion lasts

Every potion and food with an effect that runs out, at level 99 with no prayer on. A window means the effect ends somewhere inside it, because the stat timer does not start when you drink. The timer above works each one out for your own levels.

Divine potions and held boosts

How long does a stat boost last?

A boost loses one level a minute, so a super combat potion's +19 at level 99 is gone after 19 drops, 18:00.6 to 19:00 after you drink, and a ranging potion's +13 after 12:00.6 to 13:00. The first level can go almost at once, because the timer runs all the time. Combat stats, the other skills and Hitpoints over your maximum each have their own timer. With Preserve on for 15 seconds before a drop, each level lasts 90 seconds instead. Lowered stats come back a level a minute on the same timer, and Rapid Restore adds a second restore every minute from the moment you turn it on. How big each boost is at your level, and what reaches a level you need, is on the boosts calculator.

How long do divine potions last?

A divine potion holds its full boost for exactly 5 minutes, 500 ticks, and then your stat drops straight back to its level. Preserve does not change that. Each dose costs 10 Hitpoints, so you need more than 10 to drink one. Drinking a Menaphite remedy ends the hold: the boost stays and then wears off a level a minute, which is how players stretch a divine potion past 5 minutes. A saturated heart works the same way, +4 and 10% Magic held for 5 minutes, and can be used again after 5 minutes. A smouldering heart holds its boost for 2 minutes and then lets it wear off.

How long does an overload last?

Every overload lasts 5 minutes, 500 ticks: it hits you for 50 in hits of 10, puts the boost back every 15 seconds, and when it ends the boosts are gone and the 50 Hitpoints come back. You cannot drink one with less than 51 Hitpoints. The Nightmare Zone overload gives 5 + 15%, the Chambers of Xeric overloads 4 + 10%, 5 + 13% and 6 + 16%, and the blighted overload of the Deadman worlds 8 + 15% Attack and Strength while it lowers Defence. Smelling salts in the Tombs of Amascut put their boost back every 15 seconds for 8 minutes. How many overloads and absorptions a Nightmare Zone trip takes is on the Nightmare Zone calculator.

How long do antifire potions last?

An antifire potion and its mix last 6 minutes, 600 ticks; an extended antifire 12 minutes; a super antifire 3 minutes; and an extended super antifire 6 minutes. The game warns you about 15 seconds before each runs out. Every antifire needs Dragon Slayer I started.

How long do antipoison and anti-venom last?

Poison immunity runs down in steps of 30 ticks, and the first step is cut short, so it ends inside an 18-second window. An antipoison gives 1:12.6 to 1:30, a superantipoison or sanfew serum 5:42.6 to 6:00, an antidote+ 8:42.6 to 9:00, an antidote++ 11:42.6 to 12:00, an anti-venom 12:00.6 to 12:18 and an anti-venom+ 14:42.6 to 15:00. Venom immunity is shorter: 18 to 36 seconds from an antidote++, 36 to 54 from an anti-venom, 3 minutes 36 seconds from an anti-venom+ and 6 minutes 18 seconds from the extended anti-venom+. Drinking another dose never shortens what you have left. The timer stops while you have an interface open, so pause it then.

Stamina, prayer and the rest

A stamina potion or stamina mix lasts 2 minutes and an extended stamina potion 4; a charged ring of endurance doubles both, and another dose starts the time again. A prayer regeneration potion restores a Prayer point every 12 ticks, 66 in all. A prayer enhance (+) restores floor(Prayer / 2) + 31 points, one every 6 ticks at 82 Prayer and above. A blessed crystal scarab gives 8 points every 4 ticks for 40 ticks and a silk dressing 5 Hitpoints every 5 ticks for 100. A goading potion makes monsters attack you for 6 minutes, liquid adrenaline halves the cost of special attacks for 150 seconds, and a surge potion can be drunk once every 5 minutes. Hunter meats heal a second time 7 ticks after you eat them. What a prayer potion buys you against your own prayers is on the prayer drain calculator, and how many doses a stack of potions decants to is on the decanting calculator.

Free-to-play, Deadman and Hardcore worlds

Logging into a free-to-play world removes every boost except Prayer, Mining and Smithing, and members potions cannot be drunk there. On a Deadman world you cannot eat or drink for 5 ticks after banking outside a safe zone, and the blighted overload can only be drunk in a dangerous area. Hardcore worlds change no potion.

The other game timers

While you train, the aggro timer tells you when monsters stop attacking you, so you know when to reset. In player killing, the skull timer counts down how long you stay skulled and the freeze timer how long you or your target stays frozen. The item despawn timer tells you how long a drop stays on the ground.
