Backpack of Modulation

Remember that anything can be enchanted with this... Rufinell does Archon's Shrink spell on the backpack, making even Devastator Tanks the size and weight of only footballs. If this is combined with a Backpack of Incredible Volume and Featherlight, the character will be able to carry virtually unlimited amounts of stuff; 3 Thor Tanks, 2 Devastator Tanks, monster trucks, cars, anti-tank weapons...
