Most of the game data is live. Cleanup of old things & new maps will take a bit.

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
