100. Lock all the Good NPC's in the Cloakwood Mines before you flood it
99. Crush every halfling, gnome or dwarf you meet to goo
98. When you meet one of the bandit leaders in either Larswood or Peldvale, join. Get a bit comfy in the Bandit Camp, pick out your own tent, talk to the colleagues, get to know the place. Then stop playing. Congratulations! You have finished Baldur's Gate as a bandit!
97. Charm every commoner in the town and have them assemble on the town centre. Make a circle of, say, five commoners. Then make another circle of commoners around that one, and another around that one, etc., untill you've run out of commoners. Then cast a fireball spell right in the middle.
Warning: Commoners are highly flamable and should be kept away from children at all times. Burning commoners may get you into trouble with your local authorities. The fireball spell does not come with the commoners and must be purchased separately.
Please, continue!
