Diamond Flask

Diamond Flask is a flask base type that makes your critical strike chance lucky.

Effective Additional/More Critical Strike Chance
Take your critical strike chance as (x*100)%. The chance of not hitting a critical while under the effect of a Diamond Flask is: (1-x)^2. Therefore;

New crit chance = 1 - (1-x)^2 = 2x - x^2

Additional crit chance = x - x^2

More crit chance = 1 - x

Mechanics
It is impossible to roll the prefix on a Diamond Flask.
