GCDs & Cast Times

Your final cast and recast values depend on your skill or spell speed, your level, and buffs. It is one of the few formulas to include roundup.

GCD1 = ⌊ ( 2000 - f(SPD) ) × Action Delay / 1000 ⌋

GCD2 = ⌊ ( 100 - Type Y ) × ( 100 - Haste ) / 100 ⌋

GCD3 = ( 100 - Type Z ) / 100

GCD4 = ⌊ ⌈ GCD2 × GCD3 ⌉ × GCD1 / 100 ⌋ × Astral_Umbral / 100 ⌋

GCD = GCD4 / 100

Action Delay must be written in milliseconds. A 2.5 GCD, is equivalent to 2500 milliseconds.

Astral_Umbral is the cast time adjustment Black Mages factor in for Astral Fire and Umbral Ice.
