Cooldown is removed, replaced with two charges that replenish every 40 seconds.
When upgraded with Aghanim's Scepter, cooldown for both charges is counted in sequence, not independently.
40 seconds: 1 charge ready
80 seconds: 2 charges ready
新版本毒狗A杖移除了大招的CD
改为两个能量点数,这两个能量点数依次回复
也就是说用掉一个点数40秒补充,用掉两个80秒补满
