How does dota calculate magic resistance, dota Warcraft magic damage calculation

Magic damage is based on the opponent's magic resistance (all heroes are born with 25% magic resistance), the formula of magic resistance: when the hero does not carry any equipment with magic resistance, then he (she) (it) is born 25%, and if a challenge axe is equipped, when attacked by a magic damage with a damage of 100, the damage received is 100*(1-25%)*1-30%)=, and another example is an anti-mage with a challenge turban.

His own skills have 40% magic resistance, heroes are born with 25% magic resistance, and challenging the turban is 30% magic resistance, if you use a 100 damage ordinary magic to beat the mage now, then the actual magic damage he receives should be 100*(1-25%)*1-30%)*1-40%) = which means that the magic resistance is not to add up the resistance percentage, but to reduce the damage according to the resistance percentage in turn, thick. It's a bit complicated, but you should be able to understand it

Heroes start with 25% magic resistance, which is 75% of the damage taken by magic skills; Magic Resistance can be increased by equipping items: Wandering Mage's Cloak increases magic resistance by 15%, challenge turban increases magic resistance by 30%, and magic resistance stacks by 75% of the initial magic resistance x the damage ratio after the item is offset; The magic shield of the anti-mage, the accumulation of carrion of the butcher, and the ultimate of the monkey are all to increase the magic resistance; Note that the butcher, in particular, should challenge the bandana first and then upgrade the rotten flesh skill, so that the magic resistance can be stacked. Anti-mages generally don't take on challenges, let alone monkeys; Thank you.

The character's initial magic resistance is 25%, that is, the magic damage received is 75%, if you bring an anti-magic cloak, it is 75%x85%, and with a challenge, it is 75%x70% of the hero's own skills (enemy law, butcher, monkey, etc.), and then multiply.

Initial 25% magic resistance.

The back is not right, the damage is calculated like this: 1000 damage must first remove 25% of the magic resistance and leave 750, and then this 750 will be removed from the challenge turban 30%, and there is 70% * 750 = 525 actual damage. One is the magic resistance provided by the hero armor type, which is the only one.

The latter one is the magic resistance provided by the item.

The calculation is as follows:

The first level of musket is 355 magic damage. The hero has 25% magic resistance, and challenges 30% magic resistance. So the actual damage dealt is: 355 * (1-25%) * 1-30%) = So it's very simple, it's impossible to kill, even if you don't challenge it.

You can't kill it. Not to mention the health return of the challenge, you aim for seconds, the bullet flight trajectory will take at least half a second, and the challenge will return to 20 blood.

Strictly speaking, it is not a hero's magic resistance, 25% is the magic damage coefficient that the hero's armor can reduce, which means that 25% of the damage must be deducted from a skill before calculating the magic damage offset by items and skills.

Only Hero armor has a 75% magic damage modifier, and all other armor types in Dota take 100% magic damage.

And that's how the damage is counted. For example, a hero brings a challenge bandana (30%). If another hero's initial skill damage is 100, then the actual damage he takes is 100* instead of 100* (
