Name: Goddess Plume (material) Fields: Empower, Protect PWC: N/A Appearance: A crystalline object shaped vaguely like a wing, with glimmering hues of violet inside it. Function: Goddess Plumes could be used by Outfitters and Weaponsmiths. One Goddess Plume can accentuate a feature of said creation by four times- so if a Smith owned one Fire Gem and wished to forge a blade with it, using a Goddess Plume would increase the fiery power of the blade to that of a weapon containing four Fire Gems. A Splinter Crystal blade would repair itself four times as fast. A Wing Tunic with a Goddess Plume will be able to carry greater weights than a regular tunic. These rare plumes are thus prized for their ability to upgrade almost any weapon, armour, cloth or tool. Even imbuing a regular blade with a Goddess Plume will increase its ability to cut by a great deal; Goddess Plume blades are capable of felling small trees in a single strike. Goddess Plumes may also be used as talismans with similar effects, albeit weaker. A man wearing a Goddess Plume would have greater strength than one without; a Mount bearing a Plume could support the weight of even a Darknut, although with difficulty. Multiple Plumes would increase the effects- so a Mount with two Plumes could bear a Darknut with ease, and a Mount with three could bear a Lynel (although a Lynel mounting a horse would seem extremely odd...). All effects based on their use in Skyward Sword. Limitations: -These plumes would be expensive to compensate for their being extremely helpful in amplifying effects of other expensive materials -Some materials (such as Evil Crystals) will react poorly to Goddess Plumes and may even damage the creation more than aid its effectiveness. -Muscle Bands and the like would be more effective than Goddess Plume talismans for humans, although these cannot be used on Mounts.
I'm going to have to decline on your concept; while a Goddess Plume would make a great material, it... would need something more than an amplifying effect. I would be interested in accepting this, if it had a quantifiable effect (that also isn't just boosting its natural effects).
