Im going through Planescape for the first time and I'm utterly addicted to it. Ive come across a problem however. Iv heard that when you give Quell in the festhall a chocolate quasit he tells you about ravel. No dice. Iv heard that there is a sensory stone where you can speak to Ravel. I went up to the sensory stone but I got no option to speak.

What is going on? Do I have to do something else to be able to do these things?

I backtracked and talked to the master of bones and asked why Im immortal, then I could finally get the info from the sensory stone and Quell. Funny thing is I asked the Master of bones that before. Odd. Well Iv ran into another problem. I asked Kessai at the Brothel about Ravel and she says nothing. I went and talked to the abusive prostitute and she said to talk to Yves. Yves just offered a tale.

Well I got past that misfotune as well. Now yet another problem. It has always ran a tad slow when I casted a spell like Ice Knife or Ignus' Elemental Rain. But at the end of Ravel's Maze when there is the cutscene of TTO killing Ravel it just freezes and crashes form the amount of spells. iv tried 3 times. Please help me I really love this game and I'd like to finish it.
