Condition duration
That really depends if you focus on D/D or P/something. The smart thing to do is use both, each weaponset when apropriate.
People who only focus on D/D and barely use pistol bleeds don’t need much +condition duration since Death Blossom lasts 10 seconds which is quite a long while. Still, they need to make sure their +duration can be divided by 10. Every +10% condition duration is 1 extra second the death blossom bleed will tick. If you have +15%, 5% will be wasted so aim for +20% or +30% for pure D/D.
As a condi thief that does use Pistol as well as D/D I found that a good +condition duration is +50%. It’s not hard to get to, doesn’t require too much traiting (I have 15 points in deadly arts), and you still have plenty of resources left to get your bleeds to tick for 112~ so you don’t sacrifice damage for duration.
It’s important to work with increments of 25% for the Pistol, since it’s base duration is 4 seconds. So +25% means a 5 second bleed and +50% means a 6 second bleed.
Also remember that Superior Sigil of Agony stacks and you can get +20% condition duration by using two of those. I find Carrion equipment better for Condi thief than Rabid because of the pistol – you gain just as much if not more damage from bleeds by extending pistol duration to 6 seconds than you would from gaining 1 extra 5 second bleed on a 2 second cooldown (sigil of earth). Pure D/D builds might prefare +crit chance with superior sigil of earth with shorter condition durations and a chance for extra stacks.
I find that, at 80, there is no need for condition duration aside from sigil of agony and the 40% condition duration food. Well..For me that is. If the fight is going to drag out, a simple caltrops can keep me at 23-25 stacks of bleed on my own. This along with caltrops on dodge lets me just wear 2 sets of P&D (just 1 pistol and 2 daggers you can leave the other spot empty).
Anyways! I use sigil of agony on the pistol and sigil of endurance regen on weapon swap on the other one. This allows me to dodge whenever I use c&d. o.o
Im sure you would need condition duration if you did not take the “caltrops on dodge” trait. Caltrops on its own, however, will stack up to 14 times on its own if you had 100% condition duration. Add that with C&D + sneak shot + 2x autoattack, youll have 25 stacks of bleeds on your own.
