Robin scrambles to his feet, lifting the Spear and directing a thread of Earth thtough it. The Spear takes it gladly and enhances it, helping him control it while he focuses and barks out a quick incantation.
A wall of earth rises in front of him, thick and tall enough to block the Rod bearer's sight, along with his attack. Robin breathes a sigh of relief, and then the situation hits him again - he's fighting Imperial soldiers! He does not want to fight Imperial soldiers, he wants to be one!
The Spear, sensing his panic, sends him reassurance along with an offer of more earth magic. Shaking his head, he leans back against his wall and peeks out from behind it.
The townsfolk who had been watching have either run off entirely or retreated to a safer distance to watch. The town healer is fretting visibly from the group he can see huddled behind an overturned cart; she has a Pendant, but she's almost entirely focused on Life magic. None of the townsfolk are likely to be able to help him either; some of the Hunters have Lesser Artefacts, but at this time of day they're most likely out tracking down any monsters that might have gotten close to the town overnight, like the knoll he'd run into earlier.
Denes, though intimidated by the appearance of the wall, takes advantage of his distraction and his protruding head, chanting lowly under his breath as he pours a water whip into being out of his Rod. He snaps it in Robin's direction, managing to wind it around his neck and tug him the rest of the way out of the cover of the earth wall. Choking, Robin threads a nearby plant into coming to his aid, wrapping it around the Imperial mage's ankle to knock him to the ground.
Denes squeaks and shoots an ill-advised ball of weak flames at the plant with a word, catching his own pants on fire in the process. He rolls away, climbing to his feet and slapping the fire out, distracted from Robin for the time being.
Robin hesitates for almost too long, allowing his opponent to just about recover before reaching for the Spear's earth-rumble again and shooting a blunt spur of rock out of the ground to knock the Rod out of his hand, and then having his charred plant grab it and dangle it out of reach.
Artefact-less, the mage attempts a weak ice spike out of desperation, but fails. Robin levels the Spear at his chest and glances around to see how the rest of the fight is fairing.
