Lethality (4/5) - Increase opening move critical strike damage by 30%, it is very useful since you will be using openers all the time. I personally spam Sinister Strike in battle and the damage I get wow gold from this skill is my bread and butter.
Vile Poisons (2/5) - Increases the damage dealt. On paper, this talent sounds really useful. In practice though, it isn’t. It’s one of those things you only find out by playing. The 15% increase in sporadic damage is not worth the point investment.
Well, that is if you use Instant Poison instead of Deadly Poison. If you use both, this talent does gain some merit. The bonus to Envenom is nice but you won’t be using that skill as heavily as others.
Improved Poison (4/5) - Increases chance of connecting with all poisons, it doesn’t seem like much at first but this talent makes a very big difference in total output. Poisons can account for 10-15% of your total damage in a fight and the more often it hits the better. A great talent and a perfect spot to spend talent points if you wish to move lower in the tree
Improved Kidney Shot (2/5) - More damage when someone is stunned is a good thing. Unfortunately, the targets where this would give the most bosses can’t be stunned, making this talent used nearly exclusively in PvP where it’s rather low in the tree to acquire. If you are going the Mutilate route, then this is a talent you will be using.
