"First and foremost, I won't use any magic for this spar. This will reduce the risk of me accidentally killing you. I will also use no weapons, meaning that I can only use my fists." Xander spoke in a calm voice.
"Second, since I don't have much time left here, this spar will end in five minutes or when you hurt me."
"If you can hurt me before three minutes, I will give you a reward."
"I like where this is going." Leo smiled.
"Edwin, timer." Xander said without looking at him.
Edwin proceeded to take out a stopwatch and said, "I am ready."
Xander then looked at Eve and said, "I will let you start the battle, Headmistress Eve."
Eve nodded, "I will cast a fireball. The spar will begin the moment the fireball explodes."
She summoned a fireball and tossed it between them.
This fireball hovered in the air between Leo and Xander for three seconds before it exploded.
Whoosh!
Xander's figure instantly disappeared from his location.
