Backpack of Featherlight

Again, Rufinell typically enchants a backpack, but can enchant rucksacks or anything. This backpack is of extraordinary size but is very comfortable and feels like a feather. Furthermore, any objects put in are made 10 times lighter! That means that a stone weighing 20 pounds would now weigh 2. This means that with effective storage, an adventurer can store 10 times what he normally would be able to carry, including very heavy weapons and items. Even a 200 pound generator would weigh 20 pounds!
