So Giant team what we wanna do? Negotiate their surrender, fight our way though and kill the giant, or sneak in and kill the giant. If we are sneaking in Walk Unseen is a day long invisibility spell, Fell Flight is a day long flight spell, and Eldritch Glaive is an Blast shape that turns my blast into a reach weapon so I could coup de grâce the giant in his sleep though his fire shield.
