        // 这里就需要 List<string> addedAttackTargets 或 List<int> addedAttackTargetCounts
        // 来表示要添加/移除的元素。
        // 示例：如果将来有一个属性是效果列表，这里可以定义要添加的效果
        // public List<string> addedEffects = new List<string>();
        // public List<string> removedEffects = new List<string>();
        // 如果 `attackTargetCount` 实际代表可以攻击的目标ID数组，那么：

        // public List<int> removedAttackTargets = new List<int>();
        // 注意：对于 `attackTargetCount` 来说，它本身是一个 int，
        // 上面的 `attackTargetCountOffset` 已经足够处理“增加攻击目标数量”的需求。
        // "数组偏移"通常指的是当原始属性本身是一个集合时，你想要修改这个集合的元素。
        // 如果 `Attributes` 类保持其当前形式 (都是单一数值)，那么不需要专门的数组偏移。
