说实在的个人对游戏并没有多大的兴趣，但唯独对暴雪的Diablo系列很有感情，去年年初开始玩Diablo3，断断续续，感觉最麻烦的是选择技能，每次版本更新可能都有更优的build，这对于我这样的业余玩家来说可不是件好事，好在宏伟秘境后有了天梯，借鉴排名在前的高级玩家们build总没错，于是花了点时间写了这个脚本。
脚本只是统计了主动技能、被动技能和传奇宝石的使用情况，理论上统计其它如装备等信息也是一样简单可行的，但Diablo装备的生成机制使得统计这个没有多大意义，相同的装备属性可能各有优劣，难以比较，而且某些装备坑爹的掉率也不是你想要就能有的。
题外话，不得不说Python太适合写这类功能相对简单的脚本了，一个字：快。
