Grand attack potion

The grand attack potion is a combination potion that can be made at level 77 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 attack (4) and a attack potion (4), giving 155.7 experience.

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