Stats

Explaining Skill & Spell Speed

Skill and Spell Speed are a stats that affects actions in the following manner:

• Weaponskill and Spell Cast and Global Cooldown Reduction: a linear function that reduces your cast times and Global Cooldown, making you able to execute most Weaponskills and Spells faster.
• Auto Attack, DoT and HoT Strength: a linear multiplier function that increases the strength of Auto Attacks, DoTs and HoTs. It does not make them tick faster.

Its coefficient is 130 and it tiers to the 1000th (changing by 0.001).

At Level 100 each tier of Skill and Spell Speed happens every +21.3846… (2780/130) points. This means that the tiers will either be +22 or +21 points.

After the first Speed Tier, GCD tiers happen every 4 tiers from there. That is 2.49 happens at the 1st, then 2.48s at the 5th, 2.47s at the 9th, etc.

There are no buffs that directly affect Skill and Spell Speed other than increases with food.

Certain jobs have access to Haste traits and buffs, as well as Haste sometimes being available on gear. Haste affects a separate hidden Speed Modifier stat that works alongside your Speed stat to make your Auto Attacks, Weaponskills and Spells happen more quickly.

Other than the linear multiplier benefit, evaluating the full benefit of Skill and Spell Speed is arguably the most complicated problem to solve amongst all stats.

When comparing the gains on GCDs alone, it can be evaluated as a 1/1-x relationship, however, its benefit varies per job due to how many actions are affected by and benefit from the stat. The more a job has damage that is not affected by Speed, the less they tend to want it.

There are also rotation alignment and timing considerations to keep in mind, where certain values can result in potency gains be it in general or with specific encounters in mind. This is why jobs tend to target specific GCDs, recommend Speed for comfort, or choose to minimise it entirely.

Formulae

• Auto Attack, DoT and HoT Strength: f(SPD) = ( 1000 + ⌊ 130 × ( Speed - Level Lv, SUB )/ Level Lv, DIV ⌋ ) / 1000
• Weaponskill and Spell Cast and Global Cooldown Reduction (No Haste Buffs): f(GCD) = ⌊ ((GCD * (1000 + ⌈ 130 × ( Level Lv, SUB - Speed)/ Level Lv, DIV)⌉ ) / 10000)/100 ⌋

GCD and cast time values must be in ms for the formula. e.g. 2.5s GCD = 2500.

For level specific variables variables such as Level Lv, SUB and Level Lv, DIV, refer to Level Modifiers page.

Lv. 100 Spreadsheet Example

• Auto Attack, DoT and HoT Strength: =(1000+INT(130*(Speed-420)/2780))/1000
• Weaponskill and Spell Cast and Global Cooldown Reduction (No Haste Buffs): =(INT(GCD*(1000+CEILING(130*(420-Speed)/2780))/10000)/100)

GCD and cast time values must be in ms for the formula. e.g. 2.5s GCD = 2500.
