I´ve absorbed the good incarnation, but how may I absorb the paranoid and the practical one?

I think I must have a Wisdom of 20 to get over the practical one (but I don´t have). Is there a way to fight him tactically?

Did you open Pharod's sphere yet?

I´m sorry, but I´m unable to open the sphere. Maybe I don´t have enough Wisdom. Everytime I try to use it I get dizzy and have to close it again.

Weird. As far as I remember after absorbing the good incarnation you should be able to open it, since he tells you how to.

Ah well. It's been a while. I suggest you check out some of the walkthroughs at http://www.sorcerers.net/Games/Torment
There should be enough details there to help you out.

Thanks a lot. I will try it.

NOOO
absorb the paranoid, followed by the practical, then talk to the good incarnation intensely to find out who he really is.
When you absorb him, you'll become more powerful.

actually you need 21 intelligence which isn't a problem when there are so many
cranium rat charms in this game.

listen, talk to the good, find out whom he really is, then merge with him, then you can use the sphere for a massive 2000000exp points, then talk to the paranoid and talk to him in the language of the UYO then he will merge with you, then you will have enough wisdom/intelligence to overtake the practical in a battle of the wills, trust me on this one.
