Supreme ranging potion

The supreme ranging potion is a six-dose combination potion that can be made at level 93 Herblore after buying the recipe for 500,000 coins from Lady Meilyr (you do not need to find this recipe in Daemonheim). It is made by combining a super ranging potion (4) and an extreme ranging (4) in a crystal flask, giving 217.5 experience.

A dose of supreme ranging boosts Ranged by 16% of your Ranged level, plus 4, rounded down; this provides an additional 2 levels over extreme ranging at level 99 for a final level of 118.
