A guildmate and I discovered an interesting bug in Haunt that I haven't been able to find mention of anywhere. It appears Haunt will occasionally return twice the life it should when it is the killing blow or the target otherwise dies while the debuff is being applied. This actually appears in the combat log as two separate returns of Haunt from the same target.

My intuition is that it is some sort of server-client latency issue (hence it's very intermittent). It is very easy to reproduce by killing low-level NPCs with a single cast of Haunt but testing it on higher level mobs to determine the exact parameters of when this bug can be triggered has been difficult. On targets I can 1-shot with Haunt it appears to happen roughly once every 5 or 6 casts.

Has anyone else noticed this issue, and is this a known issue I've somehow completely missed discussion of?

New one tonight. Didn't see anything posted here yet, but repeated it three times tonight.

1. Cast Soulstone
2. Change Talent Sets (Activate Secondary)
3. Soulstone fades on target.
4. SS Cooldown unchanged.

So it seems that if you cast SS in one talent set, then swap to the other set, the SS fades on your target (perhaps it is the same mechanism as leaving a group). So if you juggle specs to get 2/2 Imp HS, make sure to save the SS until AFTER you summon the Soulwell.

I was looking at a WWS of my guild's most recent Hodir kill, and noticed that my Demonic Pact uptime was remarkably low. Looking into it further, I noticed that it didn't proc at all during the first half of the fight, and then seems to have procced perfectly fine for the second half of the fight. I couldn't figure out what caused this on my own, but I figure maybe someone else who is more adept at digging through WWS than I am might find something. Seeing as how there is a sudden switch from OFF to ON, I thought it might be somewhat useful for narrowing the search.

The only strange thing I noticed was that during the first half of the fight, WWS shows that Prayer of Spirit was being constantly "refreshed" on random people at seemingly random times (a total of 66 times, by my count, during the first half of the fight). Prayer of Fortitude did not do this. This random refreshing of Prayer of Spirit seems to stop just before my Demonic Pact begins to work correctly, making me wonder if the two are related. Then again, maybe it's normal for Prayer of Spirit to refresh like this and I am just forgetting something obvious.

Demonic Pact not Proccing Skip to ~3mins in and it begins to proc normally.
Strange Prayer of Spirit Refreshing

Totem of Wrath was more powerful than Demonic Pact at the start of the fight. This caused it to proc, but, not give the buff because a more powerful effect was already in place. However, at about 3'04", your Pact became more powerful through Life Tap and Spirits of the Damned all at the same time. This put the buff up and it was simply refreshed from there on out. This lead me to believe that when it's refreshed the spell power buff is NOT recalculated though, it would need more testing.

My Demonic Pact gives 274 SP with only Fel Armor and a flask, so worst case it didn't become better until I had 4 stacks of my Dragon Soul trinket up, but more likely it only took a few stacks to be better since I had raid buffs. I'm also sure that I had to Lifetap at least once before 3 minutes into the fight, so I don't think that explanation really works.

Edit: With just raid buffs and no procs, my Demonic Pact seems to give 294 SP, so better than Totem of Wrath at all times. Although on second thought, a gain of 200 spell power through raid buffs alone does seem a bit high, so it's possible I miscalculated this since I did it in the middle of an Archavon kill when I thought I had no other spell power buffs.

This should be the intended behavior. Haunt replaces previous debuff and returns to heal you, and if it kills the mob, it returns both the previous debuff and the current one that you just cast.

I didn't actually calculate anything that complicated, I simply observed my Spell Power amount before and after a Demonic Pact proc.

I'm searching blue posts on this and looking through the patch notes. All I have found so far is the acknowledgment that this is a bug in late March but no notes to say that this has been resolved. I'll get my raid's demo pact warlock to test this tonight and see if the bug is still in game.

What the guy before had said is he would get two heals from one shoting a mob with haunt, and I have noticed somthing just like this but on higher lvl mobs and the training dummy, I cast first sb then haunt and my dots, and mabey by the third or fourth refresh of haunt I will get two heals from it when it is refreshed instead of just the single heal, I also when finding this decided to let haunt drop off and got another heal like normal, no idea why this is happening but is it really a bug to mention to the gms lol

Yes it does, though it doesn't account foir demonic aegis (IE: wether or not you have the talent, demonic pact scales with 30% of your spirit while fel armor is active), this was "fixed" in 3.1. Please stop spreading misinformation- demonic pact misbehaviour has nothing to do with spellpower not being high enough as it happens in the complete absence of ToW aswell.

I have noticed this as well. I drilled down through the WWS logs on attempts where DP seems low. DP would not procc on any crit during the first 1 minute to 1:30 of the fight, and then proc. Once it procced the remainder of the fight sees the Demonic pact buff up and refreshed with every Felguard Crit.

Definately a bug, I couldn't find a trigger - loss of another buff or specific action that allowed DP to start proccing corecctly. It reduces the effectiveness of this spec for raid damage to the point i may drop it until the bug is fixed.


I checked for Prayer of Spirit but no cases of random freshes going on before or after Demonic Pact started proccing correctly.

So just to be clear, without the spirit buff Demonic Pact doesn't bug at all? I am guessing that a right click cannot remove pet buffs as that would be too easy, and I am sure you would have mentioned it.

Currently it is unknown what *exactly* triggers the bug- so it's hard to say. However I have had demonic pact bug in a party as small as 2 members (priest lock), I dont think I've seen it bug solo.

Immolate is a bit different than our other normal dots in that there are two "portions" to the damage - direct damage when it lands, and the dot effect immediately after. If you've ever cast Corruption when you had a damage buff (like a trinket proc for example), and tried casting it again before it falls off but without the buff, you will get the "There is a more powerful spell already active" message. Because Immolate has the direct damage portion, you will not get this message, even if the DOT effect already on the target is more powerful, leading to this case where Immolate will land, do the initial damage, but not refresh the dot. I don't know that I would necessarily call this a bug, but it certainly seems a bit clunky or something that could be cleaned up a bit. Until then, do your best not to clip your dots.

This is not a bug and has been stated many times in these forums. Its because you had a higher spellpower when you cast the first one. The damage portion hits, but the dot cannot override the previously casted, higher spellpower dot. Its the same as if you tried to overwrite a CoA that was casted with a trinket proc with a non trinket procced CoA.

Molson's point is that the behaviour is understood but it might still be considered a bug because the dot did not stick without a "there is a more powerful spell already active" warning.

A guildmate of mine made an interesting observation pertaining to the Demonic Pact / Prayer of Spirit bug. The two spells have spell IDs 48074 and 48090. If they're specified programatically in Hex code, that's 0xBBCA and 0xBBDA. Pretty easy typo to make for an overworked Blizzard programmer.

Its not that simple im afraid. I never had any problems with demonic pact in 25 mans(or I or any other caster never noticed them), i do in 10s though. Luckily, clicking off mass spirit buff and asking for a single one for myself seems to work for me. As can be seen here:

Although im looking through hodir tries, which im sure i clicked spirit of as we were having fun with the hardmode and it seems that it totally fails to proc? Same on freya... Some kind of wws error i guess as it was fine a week ago.

The Immolate bug is always explained with the fact that you cannot renew Immolate if a stronger Immolate is already on the target. I don't think that that is always the reason.

I was doing the tournament daily today and that happened:





I have enough hit for a normal Icecrown mob. I killed a Scourge War Engineer and switched to the next Scourge War Engineer (which was a fresh mob and therefore was not already affected by Immolate). The interesting lines are:

• The Immolate hits.
• The mob is afflicted by Immolate.
• The Immolate effect dissipates before even the initial direct damage is done.

I do use the glyph of Conflagrate, Life Tap and Incinerate. I'm skilled 3/13/55 as you can see in my profile.
I did not cast Conflagrate after Immolate because that's not possible with my latency or the latency of my server. I always cast a Chaos Bolt or Incinerate after the Immolate. Therefore it cannot be a malfunction of the Conflagrate glyph. (Also, you don't see a Conflagrate in the combat log.)

Is it possible the dissipate message is for the dead one? It would be much easier to tell if you had 2 different types of mobs, because they are the same exact mob name, lag may just mean that the "dissipate" message finally reached you based on the first one that you killed.

I cannot say for sure that the message was from this mob but I checked the combat log because I could not cast conflagrate because the Immolate did not stick to the mob. The "bug" was definitely there.

Here's another interesting thing that may or may not be related; you can have divine spirit rank 5 and 6 at the same time. The effect (+spirit) doesn't stack, however this does suggest that there's something out of whack with the debuff category of the spirit buff.
