Premeditation                       
Prerequisite Talent: 1 point in Preparation                       
Ranks: 1
Effect: Adds 2 combo points to target
You must add to or use those combo points within 20 seconds or the combo points will be lost.
Skill Duration: 20 seconds
Cooldown: 20 seconds 
If you put a point into Preparation, don’t wait another second to put a point into Premeditation. Start your combat with two extra combo points now!
Cheat Death                       
Ranks: 3
Effect: (33%/66%/100%) chance that an attack that would kill you will instead reduce you to 10% of your maximum health
All damage taken will be reduced by up to 90% (modified by resilience). This cannot occur more than once per minute.
Talent Duration: 3 seconds 
A survivability talent more suited for PvP unless you bring resilience gear for monster killing. 
The multiplier for the damage reduction is 4, but don’t count on 20 or so resilience to save you. The full formula is (4 x resilience damage reduction). At 442 resilience, that’s 22.5% damage reduction, the resilience cap. 
If you don’t have resilience, stay away from this skill until you can completely utilize it. There seems to be little benefit from this talent if you have no resilience to begin with.             
Tier 7
Sinister Calling                       
Prerequisite Talent: 1 point in Premeditation                       
Ranks: 5
Effect: Increases total Agility by (3%/6%/9%/12%/15%). Increases damage bonus of Backstab and Hemorrhage by (1%/2%/3%/4%/5%). 
For Rogues, 1 point in Agility equals approximately 1.4 points in Attack Power, .053% dodge and 0.027% critical. Added damage to Hemorrhage and Backstab already hurts, but 15% more agility? Hope you have good gear, because when you put 5 points into this, you’ll really feel the difference. 
Waylay                       
Ranks: 2
Effect: Ambush critical hits have a (50%/100%) chance to reduce the target’s melee and ranged attack speed by 20% and movement speed by 70%.
Talent Duration: 8 seconds 
Crippling Poison, minus the attack speed reduction, does the same job as Waylay. It costs you a weapon enchantment slot, but it’s a lot cheaper to replace than a full talent reset and it can happen per melee hit. And this talent is limited to daggers, but if you’re this far down the tree, you probably are using them. 
With a build that uses Shadow Dance, you might want to hang on to this. If your Ambush is a critical, then 8 seconds is long enough for you to add other stealth skills to your combo.
