Grand strength potion

The grand strength potion is a six-dose combination potion that can be made at level 75 Herblore after buying the recipe for 100,000 coins from Lady Meilyr (you do not need to find this recipe in Daemonheim). It is made by combining a super strength (4) and a strength potion (4) in a crystal flask, giving 123.8 experience.

A dose of grand strength boosts Strength by 14% of your Strength level, plus 2, rounded down. This makes it better than super strength, but worse than extreme strength.
