Diamond Luck Potion

The Diamond Luck Potion is a potion that can be made with Herblore. While active, each time the player attacks two rolls are made with the better one being used. In practice, this makes it the strongest accuracy boost available by a significant margin.

Notes

The formula for the hit chance while the Diamond Luck potion is active is

[math]\displaystyle{ \text{Potion Hit Chance} = 1 - (1 - \text{Hit Chance})^2 }[/math]

For example, a base hit chance of 75% will result in hitting [math]\displaystyle{ 1 - (1 - 0.75)^2 = 93.75\% }[/math] of the time.

Unlike other potions, Diamond Luck Potion does not get stronger at higher Potion Tiers, instead simply gaining more charges per potion. It is therefore suggested that these potions are not upgraded, as doing so reduces the total number of charges.
