I was running LoD on Lamm testing out a Vampire Vistani build Idea on my transferred character Glorei. I got to the first Tiger and remembered I had taken the Shadow Form from Shadow Dance tree.
It was displayed as a Master Form and I thought it maybe would stack with the new PM forms. Needless to say, they can't be toggled at the same time.
Seeing that, I toggled back to my Vampire form. What come next is what prompted this post.
I started to take serious Negative Energy damage, it ended up to kill me. I stopped and thought about what happened.
So I came to the conclusion that I must have killed myself, as I was the only thing 'alive' in the room and was healing myself for 700s with negative energy.
Released, I went to the Wayward Lobster. Bought some Juice and Bacon, to restore my HP/SP. I began my testing, found out quickly what was going on.
So, this is what happens:
1. Be toggled in Vampire Form (Untested for other undead forms)
2. Cast Death Aura on Self (Lesser and Regular both cause the bug. IDK about the new Enhancement Core)
3. Toggle on Shadow Form
4. Toggle Back to Vampire Form
5. Start Taking Crazy Negative Energy Damage
*6. Negative energy bust has the same effect (I think this was the massive damage I took, as it would normally heal me for 1.2k)
*7. Seems to only work in places where you can take damage (Quests/Tavern Brawls)
Testing shows that even if your Aura runs out before you swap back to Vampire Form, recasting will still kill you. Toggling the Vampire Form back off and then on again,
returns the regualr healing from Negative energy.
To add, you get a debuff when you are being effected by the Aura
