'D-dammit!' Thomas cussed, jumping through another tree. though his defensive spell did harden his muscles, it wouldn't be enough to stop a bullet in his abdomen. Thomas took out his Spell book in search for a primary healing spell. a few moments of jumping later, he found it.
'Diarama', A Healing spell which heals any pain for a long period of time. however, traces of the wound would still be found.
"This would do. . ." Thomas stopped on a tree, coughing blood. "Gods of Healing, hear thy plea. . . Remove thy pain, set thee free. Allow me to cast the spell of Healing. . . Diarama" a Green light emitted from his hand as the wound began to close. the bullet is still inside, but it wouldn't matter until the end of the fight.
"That robot's Craftier than i thought. when did technology reached this breakthrough?" he sighed, snapping his fingers. an invisible protective barrier now shields him. It'll keep him safe from any surprise attacks. "I doubt any spell i shoot can break through him. But the crystal is hard enough to break it. . ." he thought, looking  at his mage's contract. his physical affinity is rising slowly, but would be enough to substitute as bullets. Thomas jumped from tree to tree once more. his plan is dangerous, but could judging by the robot's Arm Breaking, a couple of spikes would be enough to impale him completely. now he has to find a clearing.
