I killed some tracop monsters and picked up the bronze sphere Pharud wanted. Now I went into some familiar room alone without Morte and I can't get out. There are 3 tomb keys in different tombs to find and i always get teleported. I glanced at ign and another guide but i didn't see anything that resembled what i was looking for. I don't want spoilers in the story so i didn't read those guides closely.

nevermind i didn't realize i could click on these things on the wall

I just want to add here. This has been one of teh coolest parts of the game too. And I did a lil research on the game. I didn't recall exactly but I was told to go high on Wisdom and i also went in on Int and Cha. Is there a way to know when the special dialogue options are appearing?

mm don't think so, they just show up if your stats are high enough. Some games like fallout 3/nv, etc show dialogue lines with what stat/skill is needed at what level, planescape is much older game, doesn't do that.

Never bad to go high on wisdom/intelligence/charisma for the dialogue, which will get you extra experience usually going to non-combat way. I played through with warrior thieves and still went with high wisdom/int/charisma over combat skills.

Have you read the novel by any chance? there are 2, one official and one fan made with the help of a writer i think.
