DR = Defense Rating of the defender（防御者的防御）
Special modifiers take effect when determining the chance to hit. Therefore, they affect the total attack rating and the total defense rating, not any intermediate results.
(特殊属性是在决定命中率的时候起作用的，所以，它影响的总的攻击率和总的防御率，不是任何中间结果)
Modifier Effect
Ignores Target's Defense
Treats the defender's DR as zero in determining chance to hit. ITD works only against normal monsters. (忽视目标防御在决定命中率的时候把防御方的dr看成0，忽视目标防御只对普通怪物起作用)
注：pet使用的武器具有itd时无效。
Target Defense X%
Treats the defender's DR as DR - [X / 100 x DR].
(－目标防御x％
把防御方的dr换算成dr－（x/100)dr)
-X to target defense per hit
Each successful hit reduces enemy defense by X.
(每次成功命中－敌人x的防御)
