There is a lot of mileage in such a concept, I have a character, Tessarin Sunlance, she too is an Enchanter, albeit a crabby soul “You want me to make your sword glow so that the opposite sex will find you attractive? Get out, go find some back street dust pedlar, anything that I make that glows, glows for a good reason!”
What I found was quite fun was working elements of sympathetic magic into it. If you don’t already know ‘sympathetic’ magic is the act of using ingredients or methods, that echo what you want the enchantment to do. For example Tessarin’s Hat is enchanted, It protects (Not prevents, but protects) against Mind Control. It is a battered old affair, made from leather, Rhino leather in particular, because the Rhino is a stubborn beast. the Buckle on the front is of Truesilver (I seem to remember reading somewhere that Truesilver takes enchantments very well in lore), and the lining on the inside is made from the strands of a Sayaad’s whip, again, creatures known for controlling and charming others. So you basically have an item which has elements of what you want to protect against, and how you want to protect against it, bound together with a ‘source’ if you will, in the buckle.
characters would come up to her and ask for enchants IC, and I would have a little think, then give them an ‘ingredients list’ of items I would need to do their enchantment for them, almost like a mini questgiver I suppose. If they wanted to I would even run it as a short DM’d event for them.
Basically think what the Enchantment is supposed to do, and then think what ingredients would suit it. It just adds a bit more than /e Blows some magic dust on your sword, Ta-Daaa! Magic Sword!.
Cores of Elementals are good for a lot of things, each of the four elements is traditionally associated with certain qualities, Fire being warlike, water being change, Air being intellectual and Earth being resolute and sturdy.
Animal body parts, grisly as it may sound, are also a good source of reagents. Want an enchantment that increases your perception? Why you’d want a Lynx’s Eye, and a Bat’s Ear, to be ground together and turned into a paste, mixed with powdered glass (You’d obviously want to be wearing gloves for that bit) as glass is transparent and one can see through it easily. the resultant brew to be applied to the item to be so enchanted.
Basically think of what the Enchantment is going to do, and from that work backwards as to what you think would be fitting in order to make the magic happen. Sure, use the magic dusts and stuff, but people got a kick out of the idea that they needed to get ingredients, and it wasn’t just a case of “Sure take your ticket and I’ll make your doom sword of doom for you in a minute”.
Just an idea, I find it quite fun that way, but then I am a big fan of Sympathetic Magic as a concept anyway…
