Fire (9)

Eventually, the students also joined the fray and they began to use water and Earth magic against the fire titan. However, the earth that they used only worked to increase the size of the monster, and water and ice spells only evaporated without doing much. Billy considered creating that storm and cooling down the enemy in order to make physical attacks work, but if he fails, he will waste a lot of mana. It was too risky of a plan…

Instead of that, Billy changed his plans once again. Instead of flying around the enemy, he focused on just flying in circles in front of the creature while he dodged the lava spheres and then he used Palm Cannon toward the pond on flames on the creature's chest… The best option way obviously takes out the core that was giving power to that massive creature. Billy didn't know what would happen if he achieved that, but it wouldn't be worse than letting a giant monster run around the world.
