Does a cold facet add damage to hurricane?

Yes.... If you do any form of cold damage a cold facet will add the % and -% to the enemy. ;)

It was my understanding that -%X Enemy [Element] resistance only worked when physically attacking an enemy. I couldn't find any official info on it though =\

Well I added a facet to my kira while it was on my aura din and his holy shock damage increased so Ithink it works. I remember someone saying something about not working on traps because there concidered to be minions. Seems like it worked I would also think so because i see many sorc builds suggesting the use of facets in helms and escutas. always nice to have a second opinoin though;)

Yeah I'm probably wrong :P

It's all good though.

Not sure the effecgts of facets on his cold damage but keep in mind that a lot of the damage on a wind druid is actually physical.
