Aesthetic Transformation

As part of a short or long rest you perform a ritual to transform items.
In order to perform this ritual you need to be able to control some sort of magic (Spellslots, Cantrips from Race or Arcana Proficiency).
For two hours, while remaining fully conscious and aware of your surroundings, you work to adjust the items form.

The benefits of this item or the need to attune to it do not change in any way.
This is a purely cosmetical adjustment!
