-x stack from hits the target does

What will happen when I attack a target in the "weak" state, or when a target in the "weak" state attacks me?

[Game Familiar]

Every time you hit them they lose one stack, when they hit you they substract the weakness from their attack value

But I didn't feel that I got any buff from attacking a target in the "weak" state, and the enemy didn't have any debuff either.

The weakness is applied to the damage displayed, and if you hit the enemy they lose stacks of weakness, they don't take more damage, they deal less damage to you

Is it true that if I attack a target with 4 stacks of "weakness" and it loses 1 stack of "weakness", then the damage it deals to me will be reduced by 1?

[Game Familiar]

The opposite way if you hit them they lose weakness and they hit for more

Is it true that if I attack a target with 4 stacks of "weakness" and it loses 1 stack of "weakness", then the damage it deals to me will be reduced by 1?

It will be increased by 1 per hit they do

Thanks. Maybe it's because of the Chinese translation. Now I understand it completely.
