League of Legends Ad and Ap damage calculation formula

When people often discuss it, and when searching for information on the Internet, I find that many people see a skill with double bonuses of AD\AP and say that this skill causes double physical and magic damage... .

Please, the bonus method and the damage type are completely different things! ! !

First of all, let’s talk about the current bonus methods in LOL:

1) AD bonus, that is, the damage of this skill depends on the physical attack power visible under the hero’s familiarity panel. A certain percentage conversion.

For example, if the damage bonus of a skill is (+0.5AD), then when the hero has 100 points of physical attack power, the damage of this skill will be increased by 50 points.

2) AP bonus, that is, the damage of this skill depends on a certain percentage of the spell power visible under the hero's familiarity panel.

For example, if the damage bonus of a skill is (+0.5AP), when the hero has 100 spell power, the damage of the skill will be increased by 50 points.

3) Equipment AD bonus, that is, the damage of this skill depends on a certain percentage of the sum of the physical attack power of the equipment owned by the hero.

For example, the Q and R skills of the Ominous Blade have this kind of bonus. That is, when the Ominous Blade uses AD equipment, the increased physical attack power on the equipment will be converted into a fixed percentage. Skill damage.

4) Health bonus, that is, the damage of this skill depends on a certain percentage of the total health possessed by the hero.

For example, Shen’s passive and Zhu Mei’s W are both bonuses of this type. If it is a bonus of (+0.5% health), and the hero has a maximum health of 3000 at this time, the skill’s damage will be increased. is 15 points.

5) Mana bonus, that is, the damage of this skill depends on a certain percentage of the total mana possessed by the hero.

For example, Ryze's skills all have this kind of bonus. If it is a (+10% mana) bonus, and the hero has a mana limit of 3000 at this time, the skill's increased damage will be 300 points.

The bonus is only used as the basis for the final damage calculation, but the type of damage is determined by the skill itself:

1) Physical damage will only be reduced by physical defense. No matter what kind of bonus it is, as long as the damage category is this, it will be calculated accordingly.

2) Spell damage will only be reduced by spell resistance. No matter what kind of bonus it is, as long as the damage category is this, it will be calculated accordingly.

3) True damage will not be reduced in any way. No matter what kind of bonus it is, as long as the damage category is this, it will be calculated accordingly.

Please read the description of a skill carefully. It must be a description such as "Magic damage of XXX (+X AP)". The damage category will not be determined simply by bonus!
