I am still search for items with cc res. The one I can find that are suitable for fire build are Kaisan’s eyes and Korvaak’s Decpetion.
However, switching from Absolution/ Sernerity to Korvaak’s Deception leads to a drop in DPS as a lot of damage come from Oathkeeper’s skills. And Kaisan is not easy to meet (I have only met him once after playing for half a year)
For cold resist, it is cap with +1% in game. I will still finding items that can add more elemental res
