This page provides an illustration of the use of the Damage formula, along with some recommandations for the choice of main/support summons.

Example of damage computation[edit]

Let's make up a weapon grid: for the sake of variety, we will use 1 Blushing Blossom Pin (Big Normal), 3 Colossus Cane Omegas (Big Omega), 3 Colossus Breakers (Medium Omega), 1 Balanced Blade (Big EX), and 2 Ifrit Blades (Medium Normal). Let's say everything is skill level 5.

The ATK up modifier table shows that our weapons have the following modifiers:

Add the values together by category: Normal mods = +24%, Omega mods = +51%, EX mods = +10%.

Now, to compute the Base Damage of this setup, we need to define which summon are used for main and support. Early game grids almost universally use double Elemental summons (main + support), then switch to a combination of Omega summon + Elemental summon. So let's try both.

We will suppose that:

  • Your character total ATK is 5000.
  • You have a 0★ Shiva available in the pool of support summons (+120% Elemental modifier).
  • Your two options for main summon are an Ifrit 3★ (Elemental +60%) or a Colossus Omega 0★ (Omega modifier +50%)
  • You are fighting a Wind boss, thus having a native +50% Elemental bonus for element superiority.
  • You don't use characters that provide ATK up bonuses in your team.

So, with these summon options, we can compute the resulting Base Damage.

Normal Boost = 124%
Omega Boost = 151%
EX Boost = 110%
Elemental Boost = 100% + 50% (element superiority) + 120% (Shiva) + 60% (Ifrit) = 330%
Base Damage = 5000 × 124% × 151% × 110% × 330% = 33984
Normal Boost = 124%
Omega Boost = 151% × 150% (Colossus) = 226%
EX Boost = 110%
Elemental Boost = 100% + 50% (element superiority) + 120% (Shiva) = 270%
Base Damage = 124% × 226% × 110% × 270% = 41615

In this case, it seems that using a Colossus Omega summon will be most beneficial to you. However, if you had less Omega weapons, you might want to keep using an Elemental summon.

Let's now compute what damage you can expect per hit, against a standard enemy (Innate Defense = 10). To debuff the enemy, say you use the Miserable Mist and Defense Breach skills, which stack with each other, providing a total of 45% DEF down.

The actual enemy defense drops to 10 × (1 - 45%) = 5.5, and therefore your damage per hit should be

Normal Damage = 41615 / 5.5 = 7566 DMG

That's it! If you want to go further, you will need to factor in the critical hits, the different buffs you will be using, etc. Refer to the detailed damage formula article if you want to know more.

When should I switch from double Elemental summons to Omega + Elemental?[edit]

When using double Elemental summons, there is a break point where you will want to switch to a 3★ Omega summon for your main summon, since it will outperform an Elemental main summon. This depends on two things:

  • the amount of Omega weapons in your grid and their skill level: the more you have, the more you will want to use an Omega summon;
  • which elemental summons you possess: the more powerful the summon, the more Omega power you will need before switching.

To determine the break point for you:

  • first compute your total Omega weapons modifier, without the summon (+51% in the example above)
  • estimate which Elemental support summon you can expect to find in the Summons list before the fight, and what is its aura power. As of early 2019, a good guess is 120%.
  • find, in the table below, the cell that intersects your Elemental summon aura power with the support Elemental summon aura power.

If your Omega weapons modifier is higher than the value in the cell, you should switch to a 3★ Omega summon.

On element
My Elemental
Summon
Support Elemental Summon
80% 100% 120% 130% 140%
40% 21% 19% 17% 17% 16%
50% 28% 25% 23% 22% 21%
60% 35% 32% 29% 27% 26%
80% 53% 47% 42% 40% 38%
100% 77% 67% 59% 56% 53%
120% 109% 92% 80% 75% 71%
130% 130% 108% 93% 87% 81%
140% 156% 127% 108% 100% 93%

If for some reason you are fighting off element, use this table instead.

Off element
My Elemental
Summon
Support Elemental Summon
80% 100% 120% 130% 140%
40% 29% 25% 22% 21% 20%
50% 38% 33% 29% 28% 26%
60% 50% 43% 38% 35% 33%
80% 80% 67% 57% 53% 50%
100% 125% 100% 83% 77% 71%
120% 200% 150% 120% 109% 100%
130% 260% 186% 144% 130% 118%
140% 350% 233% 175% 156% 140%

Note: Any skill that provides an Elemental ATK up effect will factor into this break point, effectively going in the direction of using the 3★ Omega summon earlier.

To know the break point with Elemental buff, know that the Elemental ATK skill effect will have the same effect as if you have a more powerful Support summon. For instance, 30% Dark ATK up with a 100% Dark Elemental summon will be equivalent for the break point as using a 130% Elemental summon with no buffs.

If you want to be precise, you can also find the break point either by solving the equation below:

(100% + X) × (100% + MyElem% + SupElem% + CharElem%) = (100% + X × 200%) × (100% + SupElem% + CharElem%)
MyElem% = Power of my Elemental summon
SupElem% = Power of the support Elemental summon
CharElem% = Total ATK up bonus provided by the character skills (and the element superiority 50% if relevant)

Solve for X, if your total Omega weapon modifier is higher than X, you're good to use the 3★ Omega summon.
