My attempt at a proc build for kin/en stalker

[Borthouth]

My build for kin/en stalker using procs where possible.

 

Build

Silentium v3.mxd

[Hjarki]

Without going through the entire build piece-by-piece, I'd start by noting that 'proc monsters' tend to work a lot better with low damage archetypes rather than high damage ones. If you find yourself making significant compromises to slot that additional +damage proc, you're probably making the wrong choice with an archetype like Stalker.

 

Also, you really want to start your journey with some critical procs:

1. Force Feedback. Properly placed, this can provide massive amounts of recharge with a single slot. Tornado (not available to Stalkers) is nearly perfect for this - it has exactly the right base recharge (60 sec) and can be cast at any time without needing a target. AE KB powers are also very strong for Force Feedback since they have a nearly automatic chance to proc if you have enough targets. You also want to be a bit careful with KB because while Overwhelming Force KB->KD is a solid enhancement, Sudden Acceleration is a waste of a slot - if you have so many knockback powers that you need to use Sudden Acceleration, you might want to re-think the build.
2. -resist procs. Achilles Heel, Annihilation and Fury of the Gladiator. The first is relatively easy to slot. Annihilation tends to best slotted in Cones so narrow that they might as well be single target attacks. Likewise, Fury of the Gladiator works best in PBAoE Cones that might as well be single target.
3. build up procs. Gaussian's, Decimation and Soulbound Allegiance. These actually have a better impact on high damage ATs than they do on low damage ATs due to the higher base damage and +damage cap. Soulbound Allegiance is difficult to slot because you ideally want to slot it into a pet with a 1 minute recharge, so it's omitted from most builds due to the lack of appropriate powers.
4. purple procs. If at all possible, you want to slot the purple procs first: Hecatomb, Apocalypse, Unbreakable Constraint, Armageddon and Soulbound Allegiance. Needless to say, slotting every one of these in a build (especially a Stalker) build is a bit difficult. But if you can slot them, they return a lot more value than the non-purple procs.

My overall impression of your build is that you have far too many attack powers. Most of the time 3 single target attack powers (including AE powers that can be used for this purpose) are sufficient. In general, you want:

1. Low Activation times.
2. 6-slotted powers - if you're going to attack with a power, you want that power to hit as hard as it can.
3. No recharge slotted into the power. You want to run almost entirely off of global recharge for attack powers.
4. Minimal-to-no accuracy slotted into the power. Similar to the above, you don't want to waste slots on accuracy when you could get what you need from global accuracy/hit.

For Stalkers in particular, most of the time the highest damage rotation will include an insta-snipe from Epic pools.

 

You will frequently find it useful to 'mule' attack powers for set bonuses. This doesn't work nearly as well with Stalkers because they really need those archetype set proc bonuses in actual attack powers, but taking a power you never plan to use just to hold the right set bonuses isn't uncommon.

 

Lastly, with any Stalker build you want to pay close attention to AE because they get so little of it. You want a big radius and 360 coverage ideally. Activation time isn't as relevant as it is for single target attacks because you don't normally create a full AE 'rotation'. However, long recharge (up to a minute) is normally beneficial. With the right amount of global recharge, these will be up for every fight and it's better to fire off one massive AE that consistently procs everything than a series of tiny AEs that don't.
