Oil of Adaptive Shape (3.5e Equipment)

Oil of Adaptive Shape
Summary::Applying this oil to a magical item causes it to change shape to still fit you when you change shape instead of melding into your new form.

Normally, magic items will automatically grow or shrink in size to match the current size of the creature wielding it. A flask of Oil of Adaptive Shape carries a potent magic of particular use to shapechangers. A single flask can only affect one wearable or holdable magic item*, regardless of the item's size. Upon application of the oil, the item not only alters size to match the wielder but shape as well. So long as the new form has an analogous body part to the previous one, the magic item changes shape to fit the new form and continues to function instead of merging into the new form and becoming inactive. This effect is permanent.

Examples:
 * A wizard using draconic polymorph wears a ring of invisibility with the oil applied to it. Since the dragon still has clawed digits on its front legs capable of wearing a ring, the ring changes size and shape to fit the new form and may still be used normally.
 * A werewolf with a Belt of Giant Strength with the oil applied to it shifts from his humanoid form into his hybrid form. Since the hybrid form has a waist, the belt remains in place around its midsection. Even if the werewolf changes to wolf form, the belt remains in place around the animal's middle, looking a little goofy but still functional.
 * A druid wearing Gloves of Spell Disruption with the oil applied to them uses his wildshape ability to become a giant octopus. Even though octopus' tentacles can grasp and manipulate objects, they are not hands, and the gloves meld into the druid's new form, becoming non-functional. Then the druid wildshapes into a dire boar, which has hooves on its front legs, and the gloves still remain melded and nonfunctional. The druid wildshapes again into the form of a deinonychus, which does have clawed hands. The gloves appear on this new shape and can be used normally.

(*The exception to the one magic item rule are item pairs such as gloves, boots, bracers, etc. that are considered a single item for enchantment purposes. In like manner, applying the oil to a suit of armor affects all of the armor's individual pieces.)
