Forum:Boss traps?

Boss traps, do they work?

Okay so I was unsure if lava traps would deal damage to a boss, since it works on other enemies, it should effect a boss as well right? I have yet to see anyone actually try this, and want to know if anyone has.

So if anyone knows if this works that would be great, and if they can tell me if its at all effective that would be great too.
