Ask about frozen

Did frozen need damage increase?(set like defiant demonic ot affix like ptl,gc,barbarian) and also did mythic effective,affix ignore resist and weaken have effect to frozen?

yes. Although mythic effective is optional​. Weaken worth it but you can also use ignore resist Although weaken is better than ignore resist when you have over 90% weaken.

Then all the things that increases damage . Frostbiting especially for the frozen to keep increasing damage so rapidly .

Oh ty,maxed frostbiting?how if i added affix like push the limit,glasscannon,or barbarian or just focus on element damage,explode,element crit,and frostbiting?
