Which Boss room can give a "special' condition or damage while you are inside of it?
Hi!
It is known that for some years the way to kill bosses increased the risks and the way to face them and one of the new conditions in some bosses is that the rooms themselves give damage or apply a condition to your character.
For example: The Pale Worm once you enter the room to face The final boss of Feaster Lost Soul, all characters receive a "Hex" which reduces your life points by 50%. (This effect can be removed using a Soulforged Lantern).
Something similar happens too (If I'm not mistaken) when you face Goshnars Malice from Soul War Quest. There is a situation where the floor got 2 colors so to avoid the damage you have to step and stay in the White SQM's until the floor came black again.

So I wanna know: What boss room gives this kind of condition that gives you a damage or some kind of curse?
Thanks in advance.
