This is the one I’ve used:

I’ve been using scavenging runes, but they’re not necessary. Some of the other runes could easily work out much better.
This build is gimmicky. The basic idea is to CnD, pop your venoms, and then apply a large amount of conditions on a target using surprise shot. When they’re locked in place, you then put some torment stacks on them, and a bit more immob when it starts to wear off.
Obviously some people will be able to clear some (or all) the condis, but in some instances the target will just be stuck there melting.
The venom sharing also means your allies get all your venoms, so it can be a really powerful thing to pack in a small scale group (i.e. 5 man roaming party).
If you want to play solo with this, I’d suggest swapping out skelk venom for HiS and BV for TG. The HiS is just necessary since it provides some condi clear and can get your opponent off you, but also allow you to initiate another stealth attack without having to CnD first. TG is useful for this build because your venom sharing will share to the other thieves. I like to try and CnD, pop TG, pop all venoms to give to the thieves, then use surprise shot on someone. The thieves then start hitting them and you basically have 3 sets of venoms being dumped onto a single target for a large amount of conditions.
Of course, if they somehow avoid or counter your initial opening, it can be problematic. In some cases it might just be better to try and only pop the immob venom first so they’re locked down, then get the others in there so you don’t waste them.
Like I said though, it’s a gimmicky build. The other builds people are posting will probably be more well rounded and viable in the long run.
