Reprisal on p12s and on delayed damage mechanics in general.

[Boys]

In P12S if I use reprisal on the cast which put "stack lasers" debuff which blow in 20 second, does it reduce damage when the debuff lasers blow even since the reprisal expired? I suppose there's only "illegal" way to check things like this really (solo and easy anyway) which I don't use. I wish things like this was more clear and didn't give advantage to ToS violators, like reprisal rather being party buff. But I suppose that would make things boring.

P.S. Please don't say I should use it on other things, I want to soften critical moments which actually wipes parties (in practice) rather then save healers a couple of gcds.

that is indeed a good question, usually it would reduce the damage of the "cast" from the boss when the cast is finished,but in this specific case, the boss fires the laser at you when the debuff expires. but 10% is a pretty low amount to test this, i suggest to keep reprisal for big AoE's that go off immediately and use other mitigation that targets your party for delayed casts.

Can’t tell if you’re asking a genuine question or just trying to sh*t stir with the way you’ve worded this post…

But the answer is the damage is reduced after the debuff expires, so you’d want to apply reprisal right before the timer ends. Reprisal snapshots the same way as any other mitigation, so if you want to test it, use hallowed ground when the mob applies the debuff and see if the damage is reduced to 0 when the debuff expires. And yes, reprisal works on damage from the debuff as long as you apply it to the mob that cast the debuff.

Too bad it's not just a mob but THE boss and I don't have many friends with that wording of mine.

The boss is a mob. Let me give you an example. In T10 you fight imdugud, a boss that applies a similar prey marker mechanic. If you apply reprisal to imdugud before the timer on the prey marker expires it will reduce the damage from erratic blaster. At certain intervals imdugud summons sons and daughters of imdugud and one of them applies a prey marker to you. If you were to use reprisal on imdugud it will obviously not reduce the damage from erratic blaster because it was one of the adds that applied the prey marker. You would need to apply reprisal to the correct add.

He's basically asking if the damage is snap shotted. It's a mechanics question, and would determine how the programming of the ability and reprisal worked.

I don't have an answer.

IIRC some fights work by spawning invisible clones of the boss to perform certain mechanics. This would also point towards the damage being snapshotted. For example:

Boss casts Quadra-Explosion. Players see the cast bar, then 4 boulders appear on the platform, which detonate in a telegraphed order over 30 seconds. Players dodge the explosions or suffer damage.
Behind the scenes, once the castbar finishes, the game spawns an invisible copy of the boss on each boulder that snapshots the current state of the boss (mitigations etc.):
Boss (1)
Boss (2)
Boss (3)
Boss (4)
This invisible, untargetable copy of the boss is the one that "deals" the damage to players for this specific castbar. As they were spawned at the end of the Boss' castbar, they are influenced by the effects of mitigation on the boss at the end of the snapshot.

Or at least, that's what I was led to believe, but I didn't really see this play out on P8S P1 with Tetraflare/Octaflare. That mechanic "stores" the cast for a good while, but I don't think snapshotting mitigation like Reprisal or Addle at the end of the cast really worked there... so maybe what I was led to believe above is wrong. Or maybe mitigations continue to tick on the invisible spawned enemies? I do not know.
