Hearing the chanting and the obvious use of magic, Rishadis moves a little towards the chants, hoping to find where they came from. As he moves beside Maven, he spots figures in the distance, north, southwest, and even more to the west. Spotting the figures north, and the ones looking like they aren't grunts, Rishadis aims for the one that looks most like their leader, hoping to end this quickly.
Chanting as he dips his hands into his spell component pouch, he conjures forth a fiery bolt, as it assails the figure to the north. There was no need to worry about hitting the figure, as the bolt appears quickly, and hits the goblin leader with both fiery force. Rishadis awaits to see what the reactions from the goblins will be when confronted with the possibility that their leader may not survive so easily.
