The CoC gem and Cospri's Malice have a cooldown. They cannot be triggered every single time you critically strike; they must wait a certain amount of time after triggering before triggering again.
This cooldown is listed as 150ms (150 milliseconds, or 0.15 seconds). This number is the subject of a lot of discussion and experiments, and is in fact ultimately accurate, but misleading.
There are a few things you have to take into account when dealing with this number. The first and foremost issue is that the game does not run on a smooth clock; the game server processes things happening in the game in regular steps, which I will call "server ticks", or "ticks" for short. These ticks are executed exactly 33ms apart when the server is running normally, and when cooldowns are checked, they are checked during one of these ticks. This means that a cooldown will delay the triggering of a skill by a whole number of ticks. If a cooldown would last for 150ms, it must wait until the next tick after that 150ms to be processed, where it can then trigger again. This means that the cooldown must wait until 165ms have passed, as that is 5 whole server ticks (33ms per tick for 5 ticks).
This means that the cooldown behaves as if it said "165ms" normally. But you can also shorten the cooldown, by getting % Increased Cooldown Recovery Speed (henceforth ICRS) on gear. You have to reduce the cooldown from the original 150ms to below 4 server ticks, or 132ms, in order to allow it to trigger again on that 4th tick. This 132ms number is achieved with a total of 14% ICRS on gear.
To achieve a cooldown shorter than 3 server ticks, you would require 52% ICRS. This is now possible in 3.9 using the Awakened Cast On Critical Strike gem, which provides 3% ICRS per level. Using a level 5 ACoC and 30% ICRS total on gear, you can speed up your casts to one per 3 ticks. Unfortunately, this ICRS is not global, and so it cannot affect the cooldown on Malice. |
