Cast Time / Delay

Overview

Cast times and delays are generally lower than official, however instant cast and 0 delay are no longer possible through only DEX and Equipment, only when combined with skills such as Memorize, Cast Ninja Spell and Poem of Bragi.

Cast Interruption

Instead of having your cast interrupted when taking any single hit, it will be interrupted if you are hit for 10% of your current HP while casting. Effects like Phen Card still work like usual, but are less mandatory.

Formula

Cast time = Base Cast Time * (30000 / (30000 + JobLevel^2)) * (10000 / (10000 + ([Dex / 10]^2 + Dex)^2)) * (6400 / (6400 + ([CTR/8]^2 + CTR)^2))

Cast Delay = Base Cast Delay * 1000 / (1000 + Delay Reduction * Delay Reduction)

• So Cast Time Reduction exists in three portions, each multiplying.
• Cast Reduction from Job Level: 30000 / (30000 + JobLevel^2)
• Cast Reduction from Dex: 10000 / (10000 + ((Dex / 10) * (Dex / 10) + Dex)^2)
• Cast Reduction from Cast time Reduction effects: 6400 / (6400 + ((CTR / 8) * (CTR / 8) + CTR)^2)

Example

A skill with a cast time of 1500 ms (1.5 seconds) at job 70 with 50% Cast Time Reduction and 100 Dex

1500 * (30000 / (30000 + 70 * 70)) * (10000 / (10000 + (10 * 10 + 100)^2) * (6400 / (6400 + ([50 / 8] * [50 / 8] + 50)^2))

=> 1500 * (30000 / (30000 + 4900)) * (10000 / (10000 + 40000) * (6400 / (6400 + 7396))

=> 1500 * (30000 / 34900) * (10000 / 50000) * (6400 / 13796)

=> 1500 * 0.86 * 0.2 * 0.46 = 119 (RO generally always rounds up)
