I'm looking at the enhancements for the assassin tree and the poisons they get. I remember them being rather... lackluster in previous updates, but now they seem to have gotten a bit of a change. The on damage, On crit, On vorpal effects seem a bit more useful, especially since there doesn't appear to be a DC for them except for the Vorpal effect.

What it doesn't tell me is how many use/day and how long it lasts, just that it has a 6 second cooldown, though it does say Melee Poison Attack, so it suggests its a Single Hit Active Ability. Still, I have a few questions about it.

1. So, looking at late game, I can expect something around a passive DC of ~30-35 with good int investment, that can be boosted higher with shiv hits and the heartseeker poison itself (every hit is -1 fort up to -5) does this make it a reliable hit? Is it worth attempting to strike a foe with these poisons or are they just clutter on my bar.

2. Are the effects substantial? Enough to warrant 3x2AP enhancements and the 3AP Toxin Affinity?. Heartseeker's -5% hp on a vorpal hit is nice And the paralasys would be cool but they get a save 25% of the time after being struck but a vorpal hit will be a KILL after a certain point. Bosses will likely have immunity or a DC too high to hit with these poisons, I doubt i'd be able to for example paralyze or shattermantle a boss. The ability damage is nice... except if its a 6 second cooldown that's maybe 1-2 applications on a TOUGH enemy, the kind it would matter on. If its a 6 second cooldown for the next FEW hits or something, then that might be nice.

3. Do they share a cooldown? Can I rotate them while one is on cooldown and the others aren't. Again this would make them a little more viable, but 6 seconds is pretty much the lifespan of trash, 10 for tougher enemies, 20 - 30 for REALLY hard ones (that are usually immune to alot of stuff)
