Note 1: +X-Y level ranges in the above list are dependant on your skill lvl. The higher the lvl, the higher the boost.
Note 2: There are more powerful boosts within certain instances, such as Tombs of Amascut-specific smelling salts, but this list only displays ones usable anywhere within Gielinor.
Note 3: Spicy stews made with the use of different colored spices (red for melee, yellow for skills, brown for ranged, etc.) provide temporary boosts to a wide range of skills. The boost from a spicy stew can range from -5 to +5, making them very versatile but also somewhat unpredictable. These should be used if you urgently need a +5 boost and do not want to spend hours leveling the skill. But on the other hand, it might take "hours" to get the RNG for correct boost. 🫠
