Grand defence potion

The grand defence potion is a combination potion that can be made at level 79 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 defence (4) and a defence potion (4), giving 146.3 experience.

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