Magic Resistance

———— [Resistance Skill].
Those are known among defensive skills as the highest class of skills.
That's because normal defensive skills all basically operate by increasing one's own defensive power. To have the skill take any incoming damage so that it wouldn't actually reach the user's body.
For example, if a person's normal defensive ability could take the attack of a level 10 opponent, then after learning a defensive skill, that defensive ability would increase, perhaps to the point where it could take a level 20 or even 30 attack.
But resistance skills are different.
Resistance skills won't increase the user's defensive ability, nor would it let the user receive damage and then mitigate that to defend. Instead, that it does is to directly weaken a fraction of the damage dealt to the user.
That's a completely different meaning from the previous example.
If it was the former, then no matter how much defensive power gets stacked on, in the end there would always be an attack that exceeds that defensive power. That's what was known as "defense break".
But resistance skills are different.
No matter how powerful an opponent's attack is, the resistance skill would always directly weaken the damage dealt.
And the higher the level the skill is, the greater the damage weakening effect is.
In other words, the former has a limit to its damage mitigation, but the latter doesn't. Be it a level 1 attack or level 100 attack, it would all get the same percentage of its damage weakened.
Only, if one wants to learn a resistance skill, one must constantly take damage until one's own body start exhibiting a certain degree of "resistance" and "immunity" to a certain type of attack before it's possible to learn. It's extremely difficult all told.
Therefore, resistance type skills are the most difficult to learn among defensive skills, but they're also the strongest defensive skills.
