Temporary skill boost

The RuneScape Wiki also has an article on: rsw:Temporary skill boostThe RuneScape Classic Wiki also has an article on: classicrsw:Temporary skill boost

This article or section requires a cleanup in order to meet the Old School RuneScape Wiki's quality standards. You can edit this page to improve it.

A temporary skill boost is anything caused by an item, action or being in a specific area that temporarily raises a player's level in one or more skills. It allows the player to do things above their current level. For example, a magic potion, which boosts a player's Magic level by four, will let the player cast High Level Alchemy (which requires 55 Magic) with a Magic level of 51 to 55.

It should be noted that temporary skill boosts do not work on certain quest and diary requirements, and do not work on minigame requirements at all.

All temporary skill boosts do not allow the player to equip items that require a level higher than their current base levels.

When logging into or world hopping to a free-to-play world, all current stat boosts are reset, except for boosts to Prayer, Mining, and Smithing.

Temporary boosts do not stack - for example, a dwarven stout provides +1 Mining and Smithing, and a mature dwarven stout provides +2 to the same skills; using them together will not produce +3, but +2, as that is the maximum boost.

Quick links

Uses

• Entering a guild that requires a certain skill level, such as drinking a dwarven stout to enter the Mining Guild. This does not work for the Warriors' Guild.
• Doing an action that requires a higher level than the player is currently at, such as using a fishing potion to fish sharks.
• Meeting the skill requirements of some quests. Players should keep in mind that temporary boosts do not work on all quests.
• Increases speed of gathering skills slightly, but visible skill boosts for these skills have no effect after level 99. For example, the dragon axe special boosts the visible woodcutting level to 102 from 99, but players will not gain any benefit from this; level 102 is the same as level 99 in terms of gathering speed.
• Conversely, invisible boosts do have an effect on gathering skills after level 99. For example, an invisible +7 boost to your fishing level inside of the Fishing Guild or a +4 invisible boost from the Celestial ring will have an impact on those respective skills.

Note: Every visible stat that is boosted will decrease 1 level every minute. For example, using a botanical pie gives a player 4 levels in Herblore but decreases in the next minute, giving the player only 3 levels. This length of time can be increased by using the prayer Preserve.

In order to check when your stats will go down again, one of the simplest methods is to drink a very cheap boost (such as beer), wait for it to decrease 1 level, then quickly use the desired boost.

The only method of stopping or pausing a stat decrease for certain skills is through a Divine Potion. Skill boosts through these potions will persist at the boosted level for 5 minutes. Once the 5 minutes are over, the player's boosted skill will be reset to the base level. Preserve will not affect this duration.

Invisible boosts

Invisible boosts are not visible on the player's stats screen, and most of them cannot allow a player to perform activities above their base level (an exception is the crystal saw). For example, the Woodcutting Guild provides an invisible Woodcutting boost of seven levels, but does not allow a player with 73 Woodcutting to chop magic trees, which require 75 Woodcutting; instead it allows the player to chop trees with the same speed as if they were seven levels higher. Invisible boosts do stack with visible boosts.

Items that give temporary boosts

• Potions, such as the hunter potion which boosts a player's Hunter level by three.
• Food, such as the garden pie which boosts a player's Farming level by three.
• Drinks, such as the Wizard's mind bomb which boosts a player's Magic level by two or three depending on the player's Magic level.
• Spicy stews - can only be accessed with completion of Evil Dave's section in the quest Recipe for Disaster. These are random and can boost OR lower a skill by up to five.
• Crystal saw, which provides an invisible boost of three to a player's Construction level. It allows players to build items as if their Construction level was three levels higher; this is an invisible boost and so can be used in conjunction with tea or stews.
• Capes of Accomplishment boost the corresponding skill level to 100/99 when the cape is equipped or operated. Prayer and Hitpoints skillcapes have a cool down period of one minute.
