Val nodded, then closed his eyes. He lifted one hand: he drew a Fire symbol in the air with his fingers, and a fireball appeared from his palm and shot forwards to Adrien, who drew an arc in front of himself - thinking of a wall of water to douse the fire. As he drew it, he focused on the feeling of his arms moving, of his fingers grasping on the staff; and, for a split second, he could see a flash of a waterfall, and the fireball sizzling away into steam as it was swallowed by the water.
Adrien breathed out. "I -- I'm not sure if I felt anything".
"Then we try again", Val said.
