說實在的個人對游戲并沒有多大的興趣，但唯獨對暴雪的Diablo系列很有感情，去年年初開始玩Diablo3，斷斷續續，感覺最麻煩的是選擇技能，每次版本更新可能都有更優的build，這對于我這樣的業余玩家來說可不是件好事，好在宏偉秘境后有了天梯，借鑒排名在前的高級玩家們build總沒錯，于是花了點時間寫了這個腳本。

腳本只是統計了主動技能、被動技能和傳奇寶石的使用情況，理論上統計其它如裝備等信息也是一樣簡單可行的，但Diablo裝備的生成機制使得統計這個沒有多大意義，相同的裝備屬性可能各有優劣，難以比較，而且某些裝備坑爹的掉率也不是你想要就能有的。

題外話，不得不說Python太適合寫這類功能相對簡單的腳本了，一個字：快。
