As an action, an object that you can touch or see within 10 meters that are not being worn or carried becomes as light as a feather for the duration. If the object weighs less than 30 kilograms, its weight is reduced to be that of a feather. If the object weighs more than 30 kilograms, its weight is reduced by 30 kilograms.
You can reduce the weight by an additional 40 kilograms for each additional mana expended.
You can expend 1 additional mana so the duration changes to 6 hours/mana.
You can expend 1 additional mana to make the object lighter only for you.
