Skill Power & Skill Power Modifier Guide

By Lady Emily.

I will attempt to explain how Skill Power and Skill Power Modifier works, as well as show how to calculate your skill’s damage. Knowing how these things work will allow you to get more juice out of your build.

Skill Power

Your base Skill Power comes from your reactor, and your reactor only. At level 100, an un-upgraded reactor will always give 11060.96 Skill Power.

The first modifier for your Skill Power will be the Optimization Condition. If you do not fulfill the Optimization Condition, you will have a multiplier of 1x meaning the Skill Power of the reactor stays the same. If it is fulfilled for a purple reactor, it is 1.4x and for Ultimate reactors 1.6x.

To see the Skill Power after the Optimization Condition modifier, go to your character’s stat page.

Inventory > [W on PC] Go to Info > Skill Power

The next modifiers will be any Skill Power Boost Ratio. You can again see this in your character’s stat page. You can often get 0.2x boosts from your reactor if you meet the condition listed. Keep in mind, this is a number added onto a BASE 1x multiplier, so the final multiplier would be 1.2x. This base 1x multiplier does not show in character stats and you have to add it yourself. Skill Power Boosts from Descendant Modules will be additively added into the numbers seen on your character stat page. Any separate relevant Skill Power Boosts are to be multiplied with each other, see example below.

Final Skill Power = [Reactor Base Skill Power] x [Optimization Condition] x [Skill Power Boost Ratio + 1] x [Skill Power Boost Ratio + 1]…

The above formula can be used to calculate your final skill power, which is not shown anywhere.

Skill Power Modifier

The Skill Power Modifier is a stat usually only found on skills with damage, and the stat is tied to the skill itself. It’s important to note the distinction between Skill Power, and Skill Power Modifier.

Below is an example of the damage calculation on a skill.

Skill Power x 112%

The 112% is the Skill Power Modifier. To use this number to calculate our skill’s damage, we convert it to decimal, in this case it’s 1.12.

Through Descendant Modules we can increase this modifier, however it is done additively as opposed to multiplicatively. If we have a module increasing Skill Power Modifier, it is shown in the character’s stat page. If we put on [MODULE] Skill Simplification and it is maxed, we get +84.5% Skill Power Modifier. In the character stat page this will show up as a decimal 0.845. We will add any increases to the Skill Power Modifier directly to the skill’s Skill Power Modifier, in this case 1.12 + 0.845 giving us a Final Skill Power Modifier of 1.965

Final Skill Damage

Your skill’s damage should be Final Skill Power multiplied with Final Skill Power Modifier. I will provide an example below.

Massive Sanguification (mod) – Dimension Damage

HP Cost = Max HP x 15%
Damage = Skill Power x 230.6%
Per 10% of HP consumed = +10% Skill Power

Above we have one of Gley’s skills. Let’s try to Calculate the damage of it.

Here’s our stats

Skill Power = 18759.39
Base Skill Power Boost Ratio = 0.081x
Non-Attribute Skill Power Boost Ratio = 1.05x
Dimension Skill Power Boost Ratio = 0.2x

Dimension Skill Modifier = 0.682x

Gley’s Massive Sanguification skill is rather unique in that it gives skill power the more HP we have consumed. At full HP, this bonus to skill power is 20%.

Final Calculation:

18759.39 x (1 + 0.081) x (1 + 1.05) x (1 + 0.2) x (1 + 0.2) x (2.306 + 0.682) = 178871.58

Base Skill Power x (1 + Base Skill Power Boost Ratio) x (1 + Non-Attribute Skill Power Boost Ratio) x (1 + Dimension Skill Power Boost Ratio) x (1 + 20% Skill Power Boost) x (Skill Power Modifier + Dimension Skill Modifier)

In testing, we can see this DOES do 178871 damage.
