Procs and Ablating Strike

I love procs and since i felt my stalker needed some more aoe damage i have put one eradication in SS and 1kCrits(also got a sciroccos proc in this)
I also have a achilles heel in ablating strike since i wanted the -res on the sweep combo.
I had begun noticing weirdness though, even though i didnt have performed a sweep combo mobs around me had the -res shields swirling around them.

So i put a lady grey in Ablating as well and monitored combat rolls

You may want to /bug this, then. Unless you're hitting multiple foes at once (Like with Sweep), Ablating Strike is single-target and should only affect a single target.

Since Ablating strike is a single target attack and ends the sweep combo, it is essentially a PBAoE that has a trigger when the combo is activated. For Procs, they will fire in the PBAoE even without the trigger. This is a feature unique to Stalker DB because all the other DBs end that combo with a PBAoE (Typhoon Edge).

This is an issue that has been known ever since they changed the combos (I can't recall for the life of me if Sweep was always like that or if it was changed to that). It's a 'fortunate' bug that may not have a solution primarily because Stalker DB don't get Typhoon Edge. Besides, we can't spam Sweep so this partways makes up for it...

So when you use Ablating attack, it procs all the foes around you? Wow.. this is cool!

how strangee.......I've never heard of that before.

Scrapper/Tanker/Brute sweep combo is 1k Cuts > Power Slice > Typhoon Edge so a stalker can't try to do their version of Sweep because we lack Typhoon Edge.

Stalker DB's Sweep Combo is BU > Assassin's Blades > Ablating Strike. The simple way to think of how the combos work is the effect of the combo is attached to the last power in a combo which will trigger when 3 other attacks are made in sequence.

Putting a proc in a combo ending attack isn't an issue for Scrapper/Tanker/Brute because pretty much every combo ends in a PBAoE or a cone. Stalker is the only one to have a PBAoE effect attached to a ST attack.

And yes, currently the proc has a chance to go off in a PBAoE (auto hit as well) everytime you use Ablating. For reference, I was told about this quirk on the forums (can't remember who now) and quickly went out to buy an Achilles heel proc for my DB/Nin, found a mass of gray/green Scrappyarders and just throw out Ablating. A little -res orange shield icon thingy would appear on a random enemies around me that I didn't hit (sometimes more than one). The defense debuff of the attack only affects the foe you target but procs work in a PBAoE. Now an interesting test is if a proc would test twice in that attack, one for the PBAoE and again for the ST.
