Questions about unique wand Obliteration

Hi all,

I was wandering about the unique modifier of the Obliteration.
It says that enemies killed will explode dealing 15% of their max life as chaos, what happens if i dual wield them? I'll deal 30% of damage by explosion?

What if i got also the unique passive of the Occultist class that give to cursed enemies a chance to explode on death dealing 25% of max life as chaos?

All of this will stack?
Do you know wich is the explosion radius?And/or if there's any chance of increase it?

I don't think two of those will stack, but it should stack with profane bloom.

Obliteration was changed and the effect is nearly exact the same as profane bloom ((cursed) enemies you kill have a 20% to explode, dealing a quarter of their health...). This wording was first used on profane bloom I think and someone of GGG said on reddit it was worded 20% and a quarter to make clear that the % chance and not the dmg would stack. So profane bloom and Obliteration should be stacking. That change was a huge nerf tho (100% to deal 15% vs 20% to deal 25% so 5% average).

Edit: And might add I think that the GGG member stated that the effects do not scale with any dmg modifiers.
