"Curse on hit" interaction with "elemental weakness on hit"?

If you use a pair of gloves with "casts elemental weakness on hit" in addition to running herald of ice + curse on hit + assassin's mark.

Does the elemental weakness override any chance the herald of ice has of applying assassin's mark therefore no power charge generation ever?
I take it the ice nova explosion of herald of ice is a "hit" that would try to apply both curses. Which takes precedence?

I can't remember which one overrides which but you'll end up with only one curse being applied either way. The only way to get the effects of both is to get +1 to maximum number of curses.

I really need to know which one overrides, im hoping curse on hit gem does otherwise ele weak gloves are useless for what im trying to do.
