Weight

This spell guards against theft by increasing the weight of a container when any creature besides the caster attempts to pick it up. This spell affects a single container, such as a chest or pouch, that is no larger than a 5ft cube. When any creature besides the caster attempts to pick up the container, the weight increases to 1d4+1 times the creature's own weight. The caster may also specify a number of creatures equal to their spellcasting ability modifier, who may also pick up the container. Picking up a creature who has picked up the pouch does not cause this effect.
