Transmogrification

Upon casting this spell, the caster may change the physical properties of the object they touch to take on different aesthetic properties:

• The caster may change the style, length, color, or volume of hair of himself or another willing creature. If cast upon a willing creature, the effects end the moment the creature desires them to, regardless of whether the caster wishes it or not. 
• An object can be manipulated in shape, but not size or density. For example a longsword can appear curved, or rune-carved with different style or design, but cannot shrink down to act or be confused with a shortsword; likewise armor and clothing can be manipulated in various styles and colors, but not make or application (ie leather armor cannot suddenly have metal studs that would change it into studded leather, or any other such mechanical values)
• Precious metals and gems can be reshaped to denominational variety, or style, but the physical makeup must remain the same (gold is always gold, rubies are always rubies).
