First off, congratulations again Sophia on making what was already a fantabulous dungeon even better. I've been soldiering through all last night and I've come accross some new areas, puzzles, items AND spells, all to my surprise.
***SPOILERS***
I have however finally ground to a halt

Which leads me onto my first question... Have you changed the Corbum Energizing Facility puzzle at all? I can't seem to do it. From what I remember, last time all I had to do was make sure that both algamams (or whatever) got hit with a fireball at the same time. I used to set the shooter off to hit the far one and I'd run up to the near one and cast FUL IR on it at the same time. Problem is that now the fireballs I cast don't work. The most logical solution is that you've changed the spell that triggers it because the spell from the shooter works on both algamams(!). I've tried every combination of spell and can't get any of them to work! HELP!
Which leads me to my next question - I've found three spells to which I have no idea of their function - ZO IR NETA seems to wipe my magic map completely for a period of time, ZO VEN (I think) brings up a message about a flask when I don't even have a flask in my hand and YA GOR won't even cast at all, which leads me to believe that it should be cast on an item... If these spells do have some function and if I'm supposed to use them in some way you need not tell me what they do, I just thought I'd point it out!
