Guild Wars 2

Simply curious…

In the chamber in which Rhendak spawns, sometimes there are drake heads on the walls, breathing fire (similar to the ones in the puzzle chamber above, which have to be disabled to open the gate). On the other hand, sometimes they aren’t there.

And far too often, when they aren’t there, I log out in the wrong place in the room, and log back in to find I’ve just been toasted to death….

Does anyone actually know WHAT controls when they’re there and when they’re not? It’s hardly a pressing matter, but I’d love to know.

I did this puzzle a few times and I never saw them not being there, or heard about it.
hmmm
