OSRS Boosts Calculator
Every temporary skill boost for all 24 skills: what each potion, pie, ale, spicy stew and special attack gives at your level, and the lowest level to boost from.
Your other levels
Some boosts need a level to use (60 Attack for a dragon pickaxe), the moonlight potion follows your Herblore and the dragon battleaxe drains Attack, Defence, Ranged and Magic.
Your situation
Some boosts depend on what happens: how hard an ancient mace or eldritch Nightmare staff hits, how many people chop your tree, how much of a god's gear you wear at a God Wars altar.

Every figure starts from your own level with nothing else active. Boosts you see on the skills tab never add together: drinking a second one only counts if it is bigger, so one summer pie bite at 85 Agility gets you to 90 and a second bite keeps you there. A figure marked ~ is an estimate, and its row says what it rests on. A use is the instant-buy price over the doses, bites or pints in one item. All 239 boosts checked against the OSRS Wiki on 28 October 2026. For the levels a goal takes, the XP calculator times every skill.
How boosts work
A boost raises the level shown on your skills tab for a while, which is enough for most quest, diary and training requirements. It drops back by one level a minute, or every 90 seconds with Preserve active. The timer runs all the time, so the first level can go sooner than a minute after you boost. Divine potions and the saturated heart hold the full boost for 5 minutes and then end at once. The potion timer works out when each boost, divine potion and overload wears off at your levels and counts them down for you. Logging in or hopping to a free-to-play world clears every boost except Prayer, Mining and Smithing.
Boosts you can see do not stack. A dwarven stout gives +1 Mining and a mature one +2, and both together still give +2. Invisible boosts, such as the Mining Guild's +7 or a celestial ring's +4, do add to a visible boost and to each other, but only make you work as fast as the higher level. The crystal saw is the one exception: its +3 lets you build things above your Construction level, so a trimmed cup of tea and a saw take you 6 levels up. Some requirements can never be boosted, such as entering the Warriors' Guild or starting Song of the Elves. The quest XP rewards calculator marks which quest requirements a boost can meet and uses the best boost from this page for each.
A drain lowers the level on your skills tab the same way, from whatever it is at the time, so a drain after a boost comes off the boosted level. Drained levels come back by one a minute, or one every 30 seconds with Rapid Restore. Some drains stack, such as a second wine, and some only land while the skill is not already lowered, such as the curse spells. The table under each skill lists every monster, place, object, spell, other player's weapon, food and drink that can lower it, with the amount at your level.
Spicy stew odds
A spicy stew raises or lowers each skill its spice covers by a random amount each time: up to 1 for one dose of spice, 3 for two and 5 for three. A bigger boost from a stew replaces a smaller one, so eating more stews never adds up past the most one stew can give. The fewest spice doses on average for each boost are in the last column. Red: Attack, Strength, Defence, Ranged, Magic. Orange: Construction, Cooking, Crafting, Firemaking, Fletching, Runecraft, Smithing. Yellow: Agility, Hunter, Prayer, Slayer, Thieving, Sailing. Brown: Farming, Fishing, Herblore, Mining, Woodcutting.
| Boost | 1 dose | 2 doses | 3 doses | Fewest doses on average |
|---|---|---|---|---|
| +1 or more | 25% | 37.5% | 41.7% | 4 (1 a stew) |
| +2 or more | — | 25% | 33.3% | 8 (2 a stew) |
| +3 or more | — | 12.5% | 25% | 12 (3 a stew) |
| +4 or more | — | — | 16.7% | 18 (3 a stew) |
| +5 | — | — | 8.3% | 36 (3 a stew) |
