4. The polymorph spell - it's about time that a spell can be used against a boss monster turning it into something like a frog. Nice to know I don't have to spend 20 minutes hacking and spellcasting away at a single monster (and then dying on the 19th minute).
Actually I cannot call it a positive aspect. It makes the game too easy when you can cast spells like Polymorph on anyone: no one is protected against spells!
