Fixed One mob killed twice at the same time

This bug has been happening for years, mostly on raids: when 2 players do fatal damage to 1 mob at the same time, it actually dies twice. There are 2 'slain' lines in the log, 2 xp messages.

But the most important implication is that any on-death scripts fire twice. In ToL, there is a raid where it matters a whole lot - Primal Vampire.

Code:

[Sat Mar 05 17:28:25 2022] The living sack of blood explodes, drawing a horde of frenzied bats to feed.
[Sat Mar 05 17:28:25 2022] A floating feast begins casting Feeding Frenzy.

There was 1 'a floating feast'. We killed it. 2 players landed the fatal blow at the same time (1 caster and 1 melee). The mob died TWICE. It gave us xp twice. It cast its on-death explosion AE twice. And it produced 2 drops in the advanced loot window: one real (can be looted) and one fake (bugged, cannot be looted).

And this happened several more times during our kill last night. It's not a rare occasion on raids. I see it all the time in any raids where we kill adds. I can provide dozens of double-kill logs from ToL raids if needed.

Can we get this bug fixed already?

Pretty bad it wasn't fixed from beta.

So getting xp twice isn't a bad thing. Not being able to loot twice, maybe expected. So whats the other bad things other than getting exploded and damaged twice? Assuming you all survive anyway.

I figure on most raids the goal isn't to get xp, you should do that as groups or quests or other things.

Would be nice to ding twice, but there are easier ways to do that outside of raids.

In what world is a raid taking double damage a good thing? This is a broken mechanic your supposed to work with and around while killing these specific mobs and dealing with other mobs / mechanics.

Don't recall seeing this yesterday, but if its legit needs fixed.

Somewhat silly post from someone who likely isn't raiding. No one who is raiding current content is caring about the experience gain from trash adds. As you can see in the log posted, the double nuke annihilated quite a few players. That is the issue, not whether someone got 0.15% of an extra aa

Yes, sorry, I don't raid. Yet. I did not realize that several players got killed in that log. It seemed out of order, but then it all happened at the same time.

I do expect that more often, in raids, be prepared to do corpse runs or summons or rez, and even lose exp or levels.

I never got to do raids, even 20 years ago when I first started playing.

In this particular raid, however, death of a charmed person is pretty much a wipe so it's a bigger issue than corpse runs, rezzes etc

Are Obiz or Rarri an enchanter?

4: Cast: Aegis of Abstraction Trigger on Rune Fade
SPA 333 (Cast on Rune Fade) is also on the enchanter Poly rune line. We were asked not to use this spell for the event. (I am guessing some other guilds had figured this out during beta).

[64008] Polyluminous Rune
1: Absorb Damage: 100%, Total: 134294
2: Cast: Polyluminous Rune Strike on Rune Fade

In all we had this occur 6 times yesterday. Each time an enchanter had the second killshot and had a rune fade spell emote.
In retrospect, I think Glyph Spray and Legion of Liako likely saved our raid if we had that many double AEs.

Obiz is an enchanter aye, nice observation

It's not that it is getting a killshot from 2 players, it's that defensive procs (like the rune procing a stun) is interrupting the death script and triggering it a second time, which is why the "slain by Enchanter" always comes before the actual player who got the killshot.

It's not unlike the whole "Ignite Blood" problem, with the difference being this is a defensive proc interrupting something else and triggering a bad thing rather than an offensive proc.


Clearly the solution is to delete all procs.

Indeed, Obiz is an enchanter, and all cases of double-kill-explosion in our Primal Vampire kill were an enchanter + somebody else.

Can confirm all of ours were as well. Our Triple AE's include 2 different enchanters and a 3rd party. 1 of our doubles includes my Enchanter I brought in for Glyph Spray that never even targeted a feast.

Can confirm looking at my logs, and I am more than happy to send my logs over to a dev.

Has anyone tested if this also is the case with druid and priests "reaction" spells?

Was able to reproduce this and it is now being tracked internally. Thank you for the report, and everyone else who contributed, it was extremely helpful!

I can also confirm from my log

Here's how this bug worked:

• NPC reaches 0 HP
• NPC death event fires. In this case, the death event causes Feeding Frenzy (450k dmg) to be cast.
• Feeding Frenzy hits an Enchanter who has a rune that has a doom SPA on it (like SPA 333 Cast on Rune Fade).
• Enchanter rune fades
• Poly Rune Strike fires (AE stun)
• Poly Rune hits the NPC
• NPC spell code is handled again for Poly Rune
• NPC HP is checked. It is 0, so we fire the death event again

Now we check if NPC HP is 0 when collecting targets in the area to be hit by the Poly Rune Strike spell (same place where distance, target type etc. is checked).

EQ has all the best bugs!

"<=0" please if that's applicable

So the bigger question is why wasn't it fixed in December when it was noted in beta?
