The following trick is a simple way to cross large gaps if you cannot figure out how to solve the puzzle (for example, catapults). Re-allocate your skill points, if needed, to equip Zoya with the low gravity arrows and Amadeus with the Conjure 2 or higher abilities. Create a low gravity field and suspend one of Amadeus's boxes within it, refire the low grav arrows, and reposition the box as needed to center the bubble over the chasm. Suspend two or more of Amadeus's boxes within the field to create a bridge. With some practice, you can move the low gravity field with you as you jump from box to box.
