So i just managed to get into the Temple of the Dead and killed the evil dogs (?), then stumbled upon two sentinels guarding massive pits of lava.
First of all, i don't recall this from the first Original Sin, but i guess its a new challenge. The problem is that i can't seem to find a way to past this segment of the dungeon.
Things i've tried already and didn't worked:
- Destroying the sentinels by using DK's vulnerability spell.
- Reaching 100 Fire Res and trying to walk over it.
- Teleporting past the sentinels.
- Using barrels and stuff to stop the pits from producing lava.
- Disarming the two pits that are closer.
- Finding a lever or button to deactivate the sentinels.
- Hiding from the sentinels; have in mind, the lava is still there even when they don't see you. When they spot you they yell their usual "INTRUDER SPIED" but nothing different seems to happen.
- Insulting my monitor.
- Crying.
So... any suggestions? I'm starting to believe that this part is rigged somehow.

Something else to add: before crossing the second bridge, there's a head-like wall that leads to another corridor, but i cannot seem to find a way to open it either. I've got a maximum of 14 perception btw, do i need more for this particular section? That would be SO cheap.
Thanks for the help!
