You can think about using a Potion of Levitation or 2 Stone of Blink (get by alchemizing 1 Scroll of Teleportation into 2 runestones). Other option would be to alchemize Telekinetic Grab Spell (Put Thrown Weapons into Liquid Metal and any scroll with any stone into Arcane Catalyst. Combine these twos to get 6x Telekinetic Grab.
