这个公式是这样的:
实际施法时间 = 1 / (速度% * (1 / 基本施法时间))
或者
实际施法时间 = 基本施法时间 / 速度%
或者
实际施法时间 = 基本施法时间 / (1 + (法术急速等级 / 1570))
注意:第一、二个公式中的“速度”代表着“每秒钟能释放的法术数量”,而“法术急速”效果会和这个“速度”相乘。
打个比方说,如果你拥有10%的“法术急速”效果(这意味着你身上的装备拥有157点法术急速等级),那么你的“速度”就是110%。然后使用公式一或者二,将“基本施法时间”代入(比如,不加天赋的顶级火球术就是3.5秒),就可以算出你实际的施法时间。
或者你可以这么想:1%的法术急速就代表着“你在平时能施放100个法术的时间内能多施放1个法术”。比如你施放的是加了5点天赋的顶级火球术,那么正常施法时间是3秒;施放100次火球术需要300秒;而1%的“法术急速”效果能让你在300秒内放出101个火球术;300/101=2.97,这就是你火球术的实际施法时间。
公式3其实是将公式2中的“速度”用“法术急速等级”进行的换算,你可以直接将你身上装备的法术急速等级相加,然后代入公式3中,算出你实际的施法时间。
This may seem counter intuitive at first. Speed is not the same thing as casting time. Speed is a measurement of casts per second, while casting time is seconds per cast. Haste is a multiplier applied to speed, in exactly the same way mounted speed is calculated. That means if you have 10% haste, your speed is 110%. In order to correctly calculate the new casting time, it must be inverted (giving you the spell's speed), multiplied by your speed %, and then inverted again (giving you the spell's new casting time.)
Another way to think of it is like this: 1% haste means you will cast 1 additional spell in the time it would normally take to cast 100 spells. If your spell is a 3 second cast, that means you cast 101 spells in 300 seconds, or 2.97 seconds per spell.
如果你知道你期望的“目标施法时间”,你也可以使用倒转过来的公式,让你知道你需要多少“法术急速等级”:
If you know how long cast you'd like a given sequence of spells to take, you can use the reverse forumla, where Base Casting Time is the sum of all the spells in the given sequence:
所需法术急速等级 = 1570 * ((基本施法时间 / 目标施法时间) - 1)
比如说,我期望我能在6.5秒之内放出2个火球术(3秒)和一个灼烧(1.5秒),那么,1570 * (((3 * 2 +1.5) / 6.5) - 1) = ~242,那么,我的装备至少需要242的法术急速等级。
Spell Haste Rating = 1570 * ((Base Cast Time / New Cast Time) - 1)
Example: I want my Fireball (3s), Fireball (3s), Scorch (1.5s) to take 6.5 seconds. 1570 * ((7.5 / 6.5) - 1) = ~242 Spell Haste Rating.

增加施法速度
许多的物品、技能和宝石能够增加施法速度。
请注意:“法术急速等级”能够互相叠加,但是这些“增加施法速度”的因素和“法术急速”是以乘法的方式作用的。比如,你一身装备的“法术急速等级”之和为157点,你就拥有了10%的“法术急速”,这和你拥有多少件增加“法术急速等级”的装备都没有关系。但是,如果你使用了巨魔的种族技能“巨魔狂暴”(增加30%施法速度),你的施法速度实际上是 (1 + 10%) * 130% = 143%。
Various sources that improve casting speed are listed on the Casting Speed improving items page.
Note: Haste rating stacks additively with itself but haste stacks multiplicatively. That means that if you have 157 haste rating, you will have +10% haste, no matter how many sources and items that haste rating comes from. If you then use troll Berserking for +30% haste, you would have 110% * 130% = 143% haste.
