Gregor scrambled up the edge of the cliff to find Evvie and Arthur engaged in an elemental sword fight. There was still some distance between him and them, so Arthur would surely see him coming if he charged in to join the battle. So instead he stayed put for now, filled his jaws with fire and immediately spat out the fireball once it was formed, aiming for it to fly past Evvie and towards Arthur. He was hoping it'd distract Arthur by forcing him to dodge, allowing Evvie to attack, or vice versa. Due to the distance, he might end up hitting Evvie depending on her movement, a risk he was willing to take due to her nature as fire creature. Even when uncharged, the fireball would explode with considerable, though non-lethal, force upon impact.
