Planescape Torment

Looking for some advice on this game. Any tips?

Hmm... if you struggle with puzzles and mazes I recommend:
Worship the Lady of Pain plushie. But you have to be sure to do this only in a save-game that has not been saved for at least three hours. It will summon an uber-item that removes all difficult puzzles.
Enjoy ^^

and subsequently kills you, best advice is to raise wisdom as high as you can then charisma then intelligence and play as a mage
