Hey @Darkir, thanks for the correction and the build. You're right, I meant Water/Poison!
(Coincidentally, I also rolled a Poison/Dark defender to see what I prefer, and I found your build in the Defender forums too.)
I'm starting to pick up on the themes for poison strategy being:
Super speed/stealth to get close to the mobs so you can...
Debuff with envenom+venomous gas+poison trap, then...
Nuke everything
By the way, is there a reason you chose not to pick up poison trap for this build, especially when we're planning on fighting up close? Is it subpar compared to the other water options?
