The giant guards at the castle gate were easily defeated. In fact, they didn't even need to fight as the side door that Ceder and the others would use was too small for giants to enter.
The Silver Knights were a tough nut to crack, and for the upcoming battle, he needed to ensure Solar didn't waste even a single Elemental Bottle.
