Any monsters immune to death effects, but not disease?

[Zumurrud]

Reason why I ask is I'm respeccing my Pale Master with the new update; I want

Force Manipulation maxed out for Horrid Wilting
Fire And Frost Manipulation to meet the minimum requirements for Blackbone Knight and Archer (Mage is useless imo)
I want Burning Blood max'd out, using either Fire or Acid spec, so that I have a good dot for boss monsters immune to insta-death.

Here's why I ask if any monsters are immune to death effects, but not disease;

If I go fire spec for Burning Blood, I don't have to spend as many AP, since I already have so much of it spent on summons AND I get meteor swarm/DBF

If I go Acid spec, I get a better Slimy Doom on contagion, which is a long term DOT (The ideal damage for boss monsters, if they weren't immune to disease), which I also like since I have my Necromancy DCs maxed out.

Bosses are immune to disease and also slimy doom is not boosted by acid spec.

[Zumurrud]

slimy doom is not boosted by acid spec.

Oh, well that closes it. Is this WAI or not?
