Lich ( Rupture The Soul ) contagion interaction

"

The Profane Bloom/Contagion thing is not technically a bug so much as a natural consequence of our skill system.

Basically, Contagion (and by extension Essence Drain) cannot spread to monsters that are 1-shot by Profane Bloom.

That's it. Monsters which are not 1-shot by PB will still spread Contagion and ED as usual. It's just that when monsters die, they do the PB explosion first then fail to spread Contagion etc later.
