Why do bog beasts die from poison?

[Argitoth]

Yeah, I watched the battle. A few died from poison. This is caused when a bog beast spits on another bog beast.

So far I've only seen battles with bog beasts on my side. I don't know how crazy this effect will get if I was to fight a bog beast army with bog beasts. What would happen is probably both sides would die from poison.

Maybe bog beasts do not naturally swallow their own saliva? Or maybe each one is unique. You never know=)

[Argitoth]

I dunno about you, but 100% resistance to poison is... 100% resistant to poison.

JK said that it's impossible to be immune to poison spit (poison resistance doesn't apply), that this is a bug, and that it's going to be fixed in the upcoming patch.

It's a know bug, poison resistence doesn't work against poison spit. Should be corrected in the first patch.
