Welcome to the Forum, Natas. It's always good to see a new face (figuratively speaking).

Dundee addressed the Backstab issue very well. The only thing I can add is that you MUST equip your weapon BEFORE you go into Stealth mode.

Also, Backstabbing is MUUUUCH more difficult in BGII. You have to actually attack from behind the target....and if you try to sneak up on a spellcaster, they will often "hear" you coming (which means you failed your Move Silently roll) and cast True Sight. Backstab is nice, but it isn't nearly as powerful as it was in BGI!
