General suggestion for the Assassinate Ability:
Works like Assassinate, but ranged and working with IPS. Thrown weapons proc a Phantasmal Killer effect on vorpal which uses your Assassinate DC (kind of like terror arrows).(Possibly only against Favored Enemies?)For 12 seconds after using this ability, your Black Wolf reduces damage it takes by 50% (the enhancement from Pale Master)
The tree has poor focus, as many have noted.
There is no +25% HP in the t5, so I assume this is intended to be a ranged tree. I imagine removing AA is more because you don't want to make this Archetype too good of a splash for ranged imbue builds, but it seems to me that removing Tempest would keep more with the theme.
I would suggest that you double down on the focus on throwing weapons and the pet for the tree.
Core 2
Level 3)
Add "Simple Throw Weapon Expertise now also applies to Martial Thrown Weapons"
Core 3
Level 6)
Smoke trap should always make them loose immunity to sneak attack, and on a failed save it should blind them. As it it is just a MUCH WORSE version of sniper shot.
Add "Multitude of Missiles now also applies to Martial Thrown Weapons"
Core 4
Level 12)
Also add Doubleshot equal to your BAB for 20 seconds if you are using a Martial Thrown Weapon.
Core 5: (Level 18)
Replace with:
+25% Sneak speed. Gain +6 Ranged Power, +6 Doubleshot, +1 insight bonus to crit chance for Martial Thrown Weapons, +1 to hit, and +1 to the DC's of your Assassinate abilities for every 1 second you remain stealthed. This effect stacks up to five times, and lasts 10 seconds after you come out of stealth. (So just a ranged version of Measure the Foe)
Your Black Wolf gains a permanent benefit of Nightshield.
Core 6 / Capstone : (Level 20)
Determine what "Cull the Weak" is.
Add:
+3 Imbue Dice

Death Attack: Ranged Assassinate. Balance TBD.
