In their natural form, the Robes of Illusion are black robes of fine quality, embroidered along the edges with faint images of magical runes, which shimmer in the light. The robes are sewn with two dozen small pockets, each of which can hold about 1/2lb of small objects without sagging, and 1lb without tearing.
At a command word, the Robes can change to look like any type of clothing or armor you desire, though, if removed, they revert to their natural form. No element of the clothing or armor can extend more than a foot from your body.
When the robes are changed to look like particularly warm or cool clothing, you resist hot and cold temperatures. When you would suffer a level of exhaustion due to cold or heat, you instead have a 50% chance of suffering the level of exhaustion.
When the robes are changed to look like particularly warm or cool clothing, you are under the effects of an Endure Elements spell.
At your option, this item functions while polymorphed or in Wild Shape.
