I'm kinda stuck on which to get for my blizz mf sorc, the reason I'm stuck is because if I go with enigma I have all that strength to help reach monarch str and could dump points into vit instead along with the big boost to MF, but if I go with COH I get the All Res and all it's goodies to help offset the sunder charm. Which would be best? and does the % to undead and demon affect Blizzard/Orb?

I would never make COH. Enigma is to good. You can get resists from charms or other gear.

Enigma has life after kill, faster run walk, and lots of MF. that's hard to get. Enigma Leagues bettter.

the % to undead and demon doesn't affect bliz or orb

Enigma

There’s really never an argument for CoH over Enigma. In any build.

Coh top1 armor

CoH is useful for certain merc builds but I agree that it's never good on the main character.

The main reason not to make CoH isnt because Enigma is always the better choice, but because if you need the resists it’s almost always worth losing the +1 skill from CoH to use Viper instead and gain the 30% fcr instead.

this, the addition of flickering flame added viable CoH merc builds for a lot of classes since its the only good way to get lifesteal on armor, which you don't have with a flickering flame + infinity setup otherwise.
but putting CoH on a sorceress is the equivalent of bringing a fury druid to a pub duel game

coh is simply a waste of a ber

Guys, just read the runes. Dol Um Ber Ist. Chains of Honor is the dumberist use of a ber rune unless using it for merc.
