ok so im curious which would be better. ive tried both and cant really tell much difference.

Amulet with the following stats

19 % damage
673 intelligence
crit hit dmg 86%
and socketed with a gem

Or

972 intelligence
97 crit damage
8% crit chance
socketed with a gem

Usually crit chance will be better. especially on an ammy where you gain 8-10 to lose 19% as opposed to a ring or bracers where you only gain 6% vs the 19 elemental

if you have 50% crit, go for chd.

always socket

ancient and crit one by far

second one not even close, especially if you skill dmg % elsewhere

always critical (chance or damage) will be better than elemental damage, elemental its just better the base status, and sometimes is not (elemental damage needs at least 40~60%+), and ur critical neck is ancient as well.. Well.. Obviously the second one is better
