Thanx to whoever answers this!

I'm in one of the rooms of the forbidden city, where i'm surrounded by three huge stones with the red, blue and green symbols on them. Oh and my exit is blocked off by a purple energy wall??! Tried blasting the stones but ended up releasing more horrors- eeks help?

Is it crucial to have the purple rune? I've come this far not knowing that i've actually missed it back in the lindsey chapter!!!

Hey, if they give you a rune that you can forget, do you think that rune is important? Well here's a little trick:
1. Save
2. Turn off
3. Turn on (after a while)
4. Load the saved game
5. Look, the door is already opened!

If you prefer to do it the hard way do this:

Put each monster (of the strongest alignement against the color of the pillars) in it's place (adertisement: monster's can turn against you so be very careful).
Here's other way:
7 point magical attack (you need to stand in the center of this room) with the strongest alignement against the bad guys, and vualá, the door is opened, in fact this is the easiest way of all.Red beat green, green beat blue, blue beat red
