At 1:11, Valeria hits a newly resurrected Tyr with Dusk of Sorrow. He dies and goes to ghost form, still showing bleeding and vampire icons. He resurrects on the next turn and then dies of the bleeding damage. I believe the bleeding and vampire effects should have disappeared upon his death, before resurrection.
An emblematic Tyr has 2 type of revives.
The skill type will cleanse.
The class type will not.
Sounds like you witnessed the latter
I watched your video, it’s exactly as @Pompitous said (I know, I’m as surprised as you that they got something right?)
The revive was caused by Tyr’s fighter class, which does not cleanse, unlike his special skill revive.
Ah, yes. Well spotted!
