Alcohol room (area/encounter idea)
Here's one for you DM's that want a flamble room, but also a lootable room if you play your cards right! The players are searching around a house dungeon, when they come acrossed a room full of alcohol barrels. When they are about half way through the room, a couple of bandits with flaming arrows pop out put from the other end of the room. When ever one of the flaming arrows/any fire base attacks, roll a 1d20, & on anyrhing above a 15, one of the barrela catch fire! If the room is lit on fire, have the fire travel around the room via the barrels & then work it's way to the center.
