I've noticed this multiple times, and it seems to only happen when you detarget or change targets (IE Festergut vomit drops your target, target swapping from Putricide to oozes, etc). I've also noticed that it seems to happen much more often during Drain Soul than anything. I've lost Corruption idk how many times during execute range.

Actually, I do remember this happening with a Succubus as well when I accidentally summoned her. I've got no idea then, as it seems to stop and start up randomly.

Yeah, I've noticed it during both those situations as well. I've recently just had it happen last night though on Rotface. I hadn't even moved since I got to my position, and had just barely gotten it up with Tricks and all. It dropped off during my Shadow Bolt spam.

Also, I've noticed something with Dark Pact. If you Dark Pact at approximately the same time as your Felhunter's Shadow Bite, his mana will update to be what he would have had if you hadn't used Dark Pact.

EDIT: Actually, the above bug is not related to Shadow Bite, I've noticed it OOC as well.

I noticed Dark Pact does not go below X% of my pet's manna in some cases. (Usualy between 40% and 50% of his maximum mana)
I have no idea why, annybody else noticed the same?
After i resummoned my pet it is normal again usualy.

Not sure why, but it seems to be when you're Dark Pacting, sometimes it doesn't display his mana correctly. It updates the bar back to what it was before you used Dark Pact, but he does only have what he's supposed to. In your case, you're probably double pacting, so the bug occurs and displays him having 40-50% mana, but he actually has much less, almost 0. Don't worry about resummoning him, it will fix itself on Shadow Bite.

Shoot (the wand ability) does not stay on while in Demon Form. You can only shoot one bolt and then have to reactivate each time to keep shooting.

[edit] Removed for now.

As someone else noted this is nothing new. However every time I've tried to reproduce this inspecting the combat log shows the 5th tick happening, so I assume it's only a visual bug.

It's lag thing. Sometimes it happens, sometimes it doesn't. The better your connection, the less likely it is to occur.

At least, that's my theory.

Posting this here as I doubt it was intended & I don't see the clever use of Demonic Teleport thread anymore.

During P2 of the Lich King encounter a warlock can set his teleport near the edge of the platform & teleport back to it after being dropped by a Val'kyr. This is very easy to set up, as the Val'kyr take you to the closest edge from where you were standing, thus eliminating the need to kill one of the Val'kyr if the warlock is targeted.

I was just looking through these forums to see if this would work. We've not had an opportunity where I was picked up and we knew we were going to wipe to check this out myself.

I understand how this is a bug, though it seems fairly obsolete since I cant think of a situation in raid where I can afford to leave Drain soul up for its duration. With haste affecting corruption and the need to refresh dots as they drop off. What tends to work well for me is to let drain soul tick a couple of times and then just before a dot falls off and just after drain soul ticks (regardless of whether it is its first tick or second) I refresh said dot and go back to drain soul.

Tonight in ICC I've been running as affliction and DS doesn't renew Corruption for some reason... even tried turning of all addons on one boss to make sure that my interface wasn't just showing it incorrect and still it didn't renew.

I experienced a similar bug in ICC 25 last night that prevented me from re-casting corruption about half-way through Marrowgar but it did not repeat.

I've experienced this bug in that instance as well, during execute time, I have to renew haunt for SE anyway, but DS does not appear to renew corruption - will take a log to see what exactly goes on.

I'll add this here because it's getting really nasty lately.
World of Warcraft (en) Forums -> [Bug] Spec switch impacts Conflagrate Glyph

At high haste levels, hero/bloodlust during the execute phase will take your corruption down from 16s to sub 8s, effectively shorter than haunt cd. There would be no way to refresh corruption with haunt at that stage. In many cases you might even have to recast drainsoul after 1 tick just to prevent corruption from dropping off.

Like Malorian mentioned, there might be some confused assumption that DS refreshes corr on ticks.

While it does not refresh on drain soul ticks, it does refresh on application. There is never a situation where you will need to recast drain soul after one tick. At worst you may need to re-cast after 3 ticks to be safe.

My experience is it not refreshing on the application, even with Shadow Bolt sometimes. Something weird happened today during trash that I've never seen before. I don't have a combat log of it, but I noticed that an Immune popped up on my scrolling combat text with the Everlasting Affliction talent icon. This occurred during a Shadow Bolt spam, and I never saw it before today.

Umm there is a bug with Demonic Aegis .. If you have it say from pvp spec and cast Fel armor and switch to pve spec you keep the bonus from Demonic Aegis gaining 140sp before raid buffs but getting a "More powerful spell is already active" error. :p

Life Tap rank 1 costs 41 health and returns 2200 mana (unbuffed, at 3400 spellpower).
The health cost is so unnoticeable that spamming it will keep you at full health and it's half the mana of a full rank.

Dark Pacts mana return is not scaling with the spellpower provided by the Glyph of Life Tap. This was reported to me yesterday and I could reproduce it ingame.

Life tap does scale properly with the spellpower provided by the Glyph
