Temporary skill drain

A temporary skill drain is an effect caused by items, monsters, weapon and ammunition special attacks or passive abilities, or interactions with scenery or the environment, which temporarily lowers a player's level in one or more skills. This can be counter-acted with temporary skill boosts or stat restoration.

Skill drain can cause the player to no longer be able to do certain actions. For example, lowering your Cooking level below 25 means it is not possible to make stew until the stat has restored to the requisite level. The Rapid Restore prayer can be used to reduce the stat change timer from 60 seconds to 30, making drained stat restoration occur twice as fast.

Some skill drains stack; drinking multiple wines will lower Attack by 2 for every one consumed, however some combat related special attacks and spells will only apply when the stat is at or above the unchanged level.

On the tables below, CurrentLevel refers to the left-side number on the skills interface and StaticLevel refers to the right-side.
