Lighten Load

This spell reduces the weight of equipment, supplies, and other objects by 50%. Weapons, supplies, and even disabled characters can all be made more portable by use of a lighten load spell.
This spell affects one pile of objects whose volume is equivalent to a 10-foot cube; after the spell has been cast, the affected objects can be divided among several characters or mounts. The spell has no effect on magical items.
An object affected by lighten load can be used normally; the spell has no effect on an object's mass, texture, size, strength, or other physical features.
