So, the covenant is trying to spend the last remaining 16 build points and they want to consider some magical items. One item that is being considered is a magic carpet. As best I can tell, carpets would be made out of Animal products, so" I went to the ReAn section, which gives "manipulate items made of animal products" as a L1 effect. So, if it is placed into a carpet, its range is personal, duration: concentration and target:individual. Then add +3 magnitudes for going fast, using the guideline for Aquam as a guide, changing extremely gentle manipulation to calm and forceful manipulation. Then add +5 to have the item maintain concentration and +10 for unlimited uses. That seems to be L20 effect.
Now, I have some idea that someplace it says that individual animal products are single strand of hair or single piece of leather, and thus I am wondering if it is supposed to be group rather than individual. However, the guideline does say "out of products" which would seem to mean that the entire rug counts under that guideline. I am currently traveling and only brought the main rulebook with me, does anyone remember something relevant?
