ice crash CoC gc Cameria inquisitor

I don't enjoy the game as much following other people's builds so I know this probably wont be my end game character. but some tips for this build are appreciated.

I came up with the idea to make an ice crash CoC glacial cascade because they're both physical to cold conversion and with hrimburn I get both the freeze and the ignite from crits. I came across the cameria mace and its prophecy in the wiki and found the free trigger interesting as additional to HoI.

I'm doing 11k damage in act 8 so far prior to switching to CoC. the only thing I see as of now is upping my attacks speed because cameria starts at 1.2 aps I believe.

ideas, tips??
