Hint 2 of 4:

Technician can't pick up the bag in its present position.

Hint 3 of 4:

You'll have to find another way to move the bag before you pick it up.

Hint 4 of 4:

Have Magician cast a spell on it, so the bag moves farther from the dragon.
Make sure to move Magician away as soon as you can.
