Help!
I'm playing as Paladin, and trying to complete the Paladin quest. So I got to Firkraag dungeon, saved the girl and sent her home, went into the maze to look around, and thats where all of my troubles started. A killed the Guardians and started collecting the skulls(not that I know what purpose is to me doing it), but just at the and, when I entered the last(hopefully last) room, I was sent to heaven. What happened is that in that last room is a Guardian who casts Sunfire,and fries my up every tima. The problem is that the Guardian is INVISIBLE, so I can't even fight him.I've tried everything but no luck. Does anyone have an idea how to kill this b****rd? How to get rid of someone ho is invisible? What am I suppose to do(apart from crying)? Please help...

You have to collect all 7 of the helmet pieces, then put in on to see him.Also, after you see him be careful, because there is a treasure chest that Samia(B****)will kill you for, so watch for her party.

if you've collected all (I think it are 7) pieces of the mask from the djinnies it becomes a mask. Put it on and walk in the room, after some time the creature becomes visible. I heard that a normal dispel invisibility works as well but I haven't tried it. (Some paladins can cast true seeing, can't they?)

Just cast Detect Invisibility or a spell of that sort if you havent assembled the mask.

Yeah you need to put together the mask, because there is an improved invisible fire elemental in there, and you can't do anything to him unless you can see him.
