Killing Spree Mechanics

[where-fore]

• [x] Do you continue to auto attack during Killing Spree? Yes, you do
• [x] Can you activate other abilities or items during Killing Spree? Spells like Sinister Strike, items like sappers? Yes to items, no to spells/abilities. It requires a macro or impeccable timing, see below.
• [x] Are Killing Spree Attacks duplicated through Blade Flurry? Yup!
• [x] Can you snapshot the damage bonus from Killing Spree to your DoT effects? Not meaningfully for Deadly Poison, potentially for other niche effects.
• [x] Can Killing Spree off hand attacks trigger Combat Potency? Yes!

Target Selection:

• [x] Is there any way to force target selection? Yes, by manipulating your range to each mob, see this note.
• [x] Are targets selected when you activate Killing Spree, or for each attack? ie. If you activate Killing Spree only in range of 1 mob, and during your Killing Spree another mob enters range, will it be able to be hit? Yes it seems so.
• [x] Are targets who die during Killing Spree still eligible targets to for attacks (wasting them)? Nope! You won't waste attacks on dead mobs.

Clipping:

• [x] Do you sometimes fall through the floor while casting Killing Spree? Can it be recreated? Nope, you generally don't. Nice!

Immunity:

• [x] Do you have some sort of immunity during Killing Spree? Can you be targeted? Can you avoid aoe mechanics? Is it just at the start during your blink, or during the entire duration? Very generally you immune movement-impairing effects for the duration of Killing Spree. Certain abilities like Maexxna's web will stun and interrupt. Specifics unclear.

Thanks to Rokman for confirming that you continue auto attacking during Killing Spree, on 6/24, ver 3.4.0.44301

[where-fore]

Thanks to Ram for confirming, on 6/29, ver 3.4.0.44369, a few intricacies of Killing Spree:

-You cannot activate other abilities during Killing Spree, even if they are off the GCD like Evasion. -Blade Flurry does indeed duplicate Killing Spree Damage.

-You can activate items during Killing Spree - notably sapper charges. The Killing Spree damage bonus is applied to the sapper. There is only a very short window where you can activate items near the start of Killing Spree. The easiest way to consistently activate a sapper and gain the damage bonus is to make a [/cast Killing Spree /cast Global Thermal Sapper Charge] macro. This works with [@player] Grenades, and likely many more items we did not specifically test.

If deadly poison is applied during Killing Spree, it will preserve the +20% bonus until the deadly poison debuff expires. When deadly poison is refreshed, it will re-check how much damage it is doing. If you refresh the Deadly Poison after killing spree expires, it will go back to doing "normal" amount of damage.

As far as I can tell there is no useful snapshotting mechanic with Deadly Poison and Killing Spree.

Re: Target Selection of Killing Spree Tests on 3/29 game ver 3.4.1.48632 (PTR)

It seems like the targets that can be hit by Killing Spree are chosen on spell cast success. In other words, a table of possible targets for every single hit of Killing Spree is built based on their range to your character on spell cast.

If you are trying to cast Killing Spree on a single target, in a clump, you can run out of the clump just to the edge of Killing Spree range, and remove some or all of the undesired targets from being added to the table of possible targets.

A video example A Weakaura to show you a table of all mobs in range of your Killing Spree if you cast it now, to help with executing this manoeuvre. A terrible MS Paint diagram:

As a side note, it seems like there is a very specific range where Killing Spree can be cast, but no targets are in range, so your character gets the buff and shadow effect, but does no damage and does not move. This is easy to recreate by standing just outside of range, and casting Killing Spree during a jump where you have spell leeway activated. If you start moving towards the mobs after a failed Killing Spree, you can salvage some of the last hits. It seems to rebuild the table from the origin of the first mob you teleport to. This has theoretical niche uses where you want to hit a very far enemy with at least a tick of Killing Spree, and there are mobs in between the two of you. You can stay out of range of all mobs, fail a Killing Spree by jumping, then walk into range of the first mob between you, and you will Killing Spree all mobs in range of the first mob between you (not your character).

[where-fore]

It has been generally known that Killing Spree does not snapshot any effects, and calculates damage for each attack separately - but I have noticed I haven't actually seen an explicit test.

So today on 6/19, PTR Game ver. 3.4.2.50063, I confirmed that Killing Spree does not snapshot attack power. I assume this will hold true for other stats like Armor Penetration and Critical Strike chance, but someone with a Runestone or Dark Matter could easily test this with the same methodology.

Damage gain from 1000 Attack Power should be about 319mh/239oh on this target: 1000 2.4/14, 1.2 for Killing Spree buff, ~1.55 for observed armor crit multi from the raw log =319 more damage with Mirror active main hand, or 239 for off hand, with some variance for weapon damage range, which looks to nicely about fit the data. Nothing fishy here, Killing Spree does not appear to snapshot Attack Power in any way.
