Just ran the numbers again (and will be posting her Seasonal Advancement to get her to where we are in that story shortly). The Thrusting Stone has an Enchantment Level of 15, and the Unseen Porter variant an Enchantment Level of 8, with no additional magnitudes for the requisites. She has Corpus 15, Herbam 10, Animal 7, Terram 5, and Vim 6, so her lowest Form is actually the base Form. Her Lab Total is 47, which enables her to do both enchantments in a single season; I didn't include the +5 Talisman Bonus for the lab work on that part, but adding a magnitude for fanciness would make the Enchantment Level 13 instead of 8.
Basically, the visual I had in mind when I originally posted this was she would use the Talisman as like a grasping claw type thing. She would reach with it, touch the crate/boulder/sheep/person/whatever, lift it with the Talisman, and move it to wherever. If that doesn't/won't work, I can drop the requisite and it won't affect the Effect or Enchantment Level any.
