The next obvious line of investigation was to check if Arokh is also fireproof (lava-proof?). Unsuprisingly, it appears that he is
- and of course Rynn isn't
, but well, we already knew that.
Curiously, some areas of the lava river in Volcano can be landed on normally, without any trickery - patches of shallow lava, perhaps?
It doesn't bother Arokh one bit... he can even walk on lava like on solid ground.
Intrinsic fire resistance?
Unfortunately, only a few of the patches are large enough to walk around on; with most of them you can only turn in place, but not move.
The patch at the coordinates above is a couple of meters long, thus walkable.
Despite the harrowing appearance (and real-world physics, but let's not go there), Rynn is perfectly safe, as long as she's riding Arokh.
But dismounting while doing that, while possible, is quite predictably a Very Bad Idea.
Sadly, no taking relaxing baths in lava for Arokh - the collision properties of the lava floor simply don't appear to permit that; and trust me, I've tried.
Also, even if it didn't hurt Arokh, Rynn would no doubt object to swimming in lava. While also catching fire at about the same time.
BTW, speaking of glitches/bugs - what's the deal with the fire breath attack? It seems to be pretty much an instakill, even on endgame enemies.
Is that something FPS-related, like applying X damage every frame?
Or does the game check each individual "puff of flame" for collision with an enemy (possibly every frame)? That would explain the extreme damage output, since there are many individual "flames" in the jet of fire.
