[Fenris is more of a useful gift person, someone who doesn't wear jewelry or carry around things that aren't useful to him, so really, Xenk's gifts are perfect for him. He was glad to have them. Jewelry is something that would be lost on him unfortunately.

He pauses when the offer to test it now is upon them. But he finds himself also unsure. What if it doesn't work? What if it only works once?]

Ah.. it is your gift to use as you please. I admit to not knowing if it will work at all or how long lasting if it does, but should it, I have a number more that are welcome to be yours.
