Abel pulled out a small round stone from his pocket. He held the stone in his hand and looked at Ikaria. Then he threw the stone in a random box on the floor. The stone landed safely, nothing happened.
"Let me lead the way," Abel said, moving onto another box, picking up the stone and marking the box with chalk.
Ikaria stood at the same box and watched Abel. Abel again threw the stone on another box, ahead of him. The stone landed on the box, suddenly a fire started only in that square box. Abel gets tensed, he pulls out another stone and throws it to the adjacent box. It was safe to move. Abel moved ahead and Ikaria moved too. He threw onto another and two swords came swinging towards them with speed. They both immediately sat.
"Are you alright?" Abel asked.
Ikaria nodded.
"It will be over soon," Abel said, throwing another stone.
