The following information is the general formula used to calculate how damage works, including everything scoping it (sparks, ATK boosting abilities, ATK boosting items, etc). Such information is helpful to answer the questions of wondering players.

Damage Formula
ATK * (1.0 + S + LS1 + LS2 + P + O + aBB + BB) * C * E * S

ATK = Attack Stat

S = Sphere boost

LS1 = Your leader skill

LS2 = Friend's leader skill

P = ATK Potions

O = ATK Ores

aBB = ATK Buffing BB

BB = Attack BB

C = Critical instances

E = Elemental Affinity

S = Spark instances

Unit Example
.

Name: Ryujin Mifune

Type: Breaker

Level: MAX

Sphere: Angelic Foil.

Attack Stat (ATK)

 * This is the general attack stat of your unit.

Sphere (S)

 * ATK boosting spheres like Holy Blade (10% initial* ATK boost), Muramasa (50% ATK boost for first 2 turns), Hero Stone (20% ATK boost if BB Gauge is above half), Angelic Foil (75% ATK boost for first 2 turns), Cordelicite (10% initial* ATK and DEF boost), and etc. apply here.
 * Mifune is equipped with an Angelic Foil, granting him 75% ATK boost for 2 turns. 75% is also 0.75, thus S = 0.75.

* Initial means that the boost is applied directly to the stats, unlike Muramasa and Angelic Foil, wherein certain conditions should be activated for them to be applied.

Leader Skill (LS1 and LS2)

 * This refers to your Leader Skill and your Friend's Leader Skill, meaning they stack. Meaning, having to Holy Flame Vargas's as leaders grants you a total of 100% ATK boost to your Fire units.
 * Assuming that Mifune together with 4 of his teammate units and an Unholy Magress friend, this means that Mifune will have 50% ATK boost, thus LS1 = 0 and LS2 = .5.

ATK Potions (P)

 * This refers to the 30% ATK Potions only at the moment, for other Potions like that one is still unavailable (50% ATK Potions are going to be released in the future updates). However, note that there is only one "P" in the equation. This means that it is impossible to have two 30% potions or one 30% potion and one 50% potion active at the same time. The latter potion will replace the effect of the former, unlike leader skills, which stack.
 * Assuming that you used a 50% ATK Potion on Mifune, this means that P = 0.5.

ATK Ores (O)
​
 * Elemental Ores are calculated here.
 * Note that "P" and "O" are separated, this means that attack potions and ores DO stack, so if you used a 50% ATK Potion and a Dark Ore, together (P & O) they are calculated and stacked.
 * Assuming that you also used a Dark Ore (50% ATK boost for 3 turns) for Mifune's team, this means O = 0.5.

ATK Buffing BB (aBB)

 * This covers the BB's of units like Weiss' (increasing all units ATK by a certain percentage), and Lancia's (increasing all units ATK by a certain percentage + heal). The value of this factor will depend on the unit that uses the BB and the BB level of the unit. Note that there is only one "aBB" factor, this means that multiple ATK buffs will NOT stack.
 * Assuming Mifune has Lancia on his side, with a certain BB level allowing her to boost everyone's ATK by 120% and heal, aBB = 1.2.**

** The details shown above is just an example, it is unkown whether Lancia boosts that percentage.

Attack-type BB (BB)

 * This is the boost in damage a unit does with an attack-type BB.
 * Every unit's BB has a different "BB" value that is calculated here. Some units have a large value (i.e. Death God Lodaga), while others have a smaller one (i.e. Hell Keep Alice). Keep in mind that while Alice's BB has a smaller "BB" value, the damage dealt is to everyone; whereas Lodaga has a large "BB" value, that damage is only dealt to a single target​. This is the value that changes when you level up BB​.
 * Mifune has an AOE BB, thus smaller BB value, but affects everyone. Let's assume his BB = 250, meaning he does an average of 250 damage per hit for 6 hits without any spheres, thus, he can deal a total of 1500 damage.**

** Assumptions only.

Critical instances (C)

 * A critical hit will add a 1.5x multiplier to the total damage
 * Can be modified with "Boost in critical hit damage" leader skills like Duel-SGX.
 * Assuming Mifune brought a Duel-SGX, granting 70% and above critical hit rate (CHR) and Mifune triggers such effect, his ​C = 1.5.

Elemental Affinity (E)

 * Attacking a unit that you have an advantage over will add a 1.5x multiplier (greater) to the total damage; whilst, attacking a unit that you have a weakness to will add a 0.5x multiplier (lesser) to the total damage.
 * Assuming Mifune attacks a pure light team, wherein he has advantage at, his E = 1.5.

Spark (S)

 * A spark will add a 1.5x multiplier to the damage dealt.
 * Note that this 1.5x multiplier affects only the hit that actually sparked​
 * Can be modified with spark damage boosting leader skills.
 * If Mifune is made as a leader, spark damage will rise greatly. For computation purposes, assuming that he isn't, and in his 6-hit BB he sparked 3 times, this means his spark damage will be three times 1.5 thus S = 4.5.

Example Computation
ATK * (1.0 + S + LS1 + LS2 + P + O + aBB + BB) * C * E * S = 2109 * (1 + .75 + 0 + .5 + .5 + .5 + 1.2 + 500) * 1.5 * 1.5 * 4.5

= 504.45 * 1.5 * 1.5 * 4.5

= 5107.55625

= 5108

This only means that Mifune will do a maximum 5108 damage per hit IF all conditions are triggered especially the Sparks, Elemental Affinities, CHR and the ATK boosting spheres and items.
