I Cast Fireball
When a wizard says 'I cast fireball!' it's usually a sign they're either desperate or just really angry. Either way, the room is about to feel the heat.
'I cast fireball!' The wizard was mad. The room exploded. Everyone died. Even the wizard.
'I cast fireball!' He said it like he meant it. The fireball hit the wall. Everyone got burned. Even the wall.
'I cast fireball!' He said it three times. The fireball hit the ceiling. The ceiling fell. Everyone got crushed.
