Seeing that I am asking for help regarding the final chapter of the game, I suppose I'll throw up a general SPOILER WARNING. However, I don't really see this getting into story stuff. Double however, if you're commenting on this you've probably beaten the game.
I started playing Eternal Darkness earlier this year, but after taking a lengthy break I decided to wrap it up this morning. I'm in the final chapter as Alex and I am currently activating the various pillars to summon an Elder to counter Pious's. Pious is aligned with Xelo'lotath (Green), which makes my dominant alignment Chattur'gah (Red). I am up to the 6th pillar, moving from left to right, which was yet another Pargon rune. After dropping a Pargon onto the 6th tower I am warped into a room with three large pillars, not unlike the one the vampiritic creature fed off of in the Edward Roivas chapter. Each of the three pillars is engraved with each of the elder gods' symbols (Green, Blue, Red), and I must destroy all of them to take down the purple barrier and continue.
Every walkthrough I have found says that I need to use a Mantorok-aligned 7-Point "Attack Magick" spell while standing in the center of the room to destroy all three of the pillars at once. The only problem is that I DO NOT HAVE a Mantorok alignment! Apparently I missed getting it back in the Edwin Lindsey chapter and do not have an earlier save. Every time I attempt to attack individual pillars with a properly aligned Attack Magick or an enchanted weapon the other two pillars feed the pillar I am attacking with energy to summon a Horror. I have even attacked all three individually in an attempt to get the horrors to fight each other to no avail.
So, is there a way I can take out these pillars without the Mantorok rune?
I have found several posts that state that the Mantorok rune is optional, but have been unable to find any walkthrough or video that shows someone dealing with this room without it.
Here is a video of where I am at in the game (being beaten with the Mantorok rune): http://www.youtube.com/watch?feature=player_detailpage&v=vnEgnoClwkQ#t=183s

Any help would be much appreciated. Thanks.
