Well, after testing in game and reading about it (here: https://goo.gl/3FaVCX), I'd like to know why the sword have been nerfed in iRO servers.
It used to work in pRO and it still works in kRO (see a guilde for the build on kRO server here: http://goo.gl/GIJ6oK).
It doesn't proc anymore when using coldbolt from another source, and it would be great to have it back since the job doesn't have much fun in terms of pvm experience.
Thank you!!
