Re: Treachery, Chains of Honor or Fortitude?
I agree with -'s.
Chains is often considered inferior to Fortitude because Fort boasts the huge damage bonus. However, keep in mind that Chains offers 200% damage to Demons and +2 skills.
Now, I know that 300% across the board will certainly increase your killing speed compared to the class-specific damage from Chains (though whether or not the increase in efficiency is very noticeable is up for debate.)
Regardless, Demons are the clear and present danger. Most undead are quite slow and not very threatening to a Barbarian, save for gloams and the like. but even then the extra resist covers that. But realistically, since all act bosses, Frenzytaurs, all pandemonium quest bosses, ~60% of Baal's minion wave and prbably more than half the other creatures in the game are Demons, already we see Fort only beating Chains by a margin of 100% damage.
Of course, in your case, the extra +2 skills would give you +10% damage from mastery and 10% for Frenzy, so now Fort is only winning by 80%.
Then of course there is the huge defense bonus a barb will get if the Frozen Armor triggers. This is of course fantastic. If you really need defense, Fort may be better.
But as far as I am concerned, without the FA proc for the defensively challenged, Chains beats Forts all day. I mean, especially for a barb, where the +2 all skills translates to more life, mana, stamina, damage, defense, attack rating, running speed, resist and chances for a critical strike. Then you slap on way more resist, magic find, LEECH (HE-LLO!), replenish life and 20 strength (20% more damage by the way, so really Fort just has Chains beat by 60%) and Fortitude is left in the dust.
I guess go with Chains of Honor is what I am saying.
