Cast on Freeze nerfed but also bugged?

Hi all,

maybe I do not understand how this skill is working, so please tell me what I am missing.

I tested Cast on Freeze with one regular mob which should have 1 power I guess (since the energy gained is based on the power of a mob).

I am using Comet on my Cast on Freeze, so I need 100 Energy to get it cast (10 energy per 0.1 seconds cast speed on 1 second cast speed on Comet).

The skill gains 10 energy per frozen Enemy.

I have Impetus as support gem which gives me a 40% increase of energy gained.
The skill itself says 33% increased energy gained.
Last but not least I have spell echo which lowers the cast speed to 1.3 seconds.

So in theory I should get around 17 energy per frozen enemy? (10 * 77%).

17 of 130 is 13%.

But after freezing one regular mob it went from 76% to 84%. So only 8%. How is this possible? Is my math so wrong?


What do you guys think?


Edit: hm, I now see that there is a +1 seconds to cast time also written on ice comet. So if this is added to the base 1 seconds, maybe the 7% would be plausible. But why is the cast time not just written in total time then?

Ok, next thing I found out now is, that in the details tab of the skill I can see that my naked Cast on Freeze has 300 energy. But the cast speed is still 1.0 secs + another second. So it should 200 energy. Very weird...
