This long, flowing cloak is sewn from an assortment of chromatic dragon scales.

While wearing this cloak, you have resistance 5 to an energy type of your choice (acid, cold, electricity, or fire) provided that you are chaotic evil, neutral evil, or chaotic neutral. You can select or change the resistance by speaking the command word.

Relic Power: If you have established the proper divine connection, you can also transform a dragonscale cloak into functional dragon wings upon command.
The wings (which last for 2 hours per day, divided up as you wish) allow you to fly with a speed of 60 feet and average maneuverability. Additionally, the value of the cloak’s resistance to energy increases to 20.
To use the relic power, you must worship Tiamat and either sacrifice a 6th-level divine spell slot or have the True Believer feat and at least 11 HD.

Lore: The first dragonscale cloak is said to have been created from the scales of Tiamat herself by a devoted high priest who visited the dragon queen on her home plane. Since then, those who ally with evil dragons have occasionally collected assortments of scales with which to duplicate the process (Knowledge [religion] DC 20).

Prerequisites: Craft Wondrous Item, Sanctify Relic, polymorph, resist energy.
Cost to Create: 2,500 gp, 200 XP, 5 days.
