So, he wasn't going to come quietly?  Irksome, but not so unusual for powerful individuals such as this.  Johannes fell silent, offering no immediate response to his target's challenge.  He would no longer waste time trying to negotiate.  From here onwards, things would be decided in a simpler, more brutal manner.

He strode forwards, moving roughly towards where Thomas had shot his spell up into the air.  Mechanisms shifted within the drone body, as he diverted power to its right arm, charging some of the more dangerous systems concealed within.

His opponent had gone and showed off his location by firing that shot in the air, obviously attempting to draw notice.  But was he so overconfident as to lead the drone directly to him?  Johannes doubted it.  That meant the shot was a diversion, and attempt to attract the drone precisely where Thomas wanted it and expose it to an attack.  The mage himself would be moving, likely prepared for a direct assault.

The engineer, however, had other plans.  The drone body was certainly powerful enough to resolve matters through brute force, but its master preferred to work with a hint of subtlety.

As he drew nearer where the spell had been fired off, he changed course.  Instead of directly approaching its location, he moved leftwards, slowly and carefully altering his route.  At the same time, he was watching at listening, and quickly found the hint he was looking for.  Jumping from tree to tree certainly made one hard to keep track of, but unlike Johannes' cautious plodding, it was not a quiet means of travel.  Though there was no way for Johannes to immediately pinpoint the location of one who was moving so fast, the shifting of leaves and the [i]thud[/i] of feet against bark were clear signs of what his opponent was doing.

Time for him to set a trap, then.

The drone had been recording all that it saw on its march through the jungle, and storing that information for later use.  Now, the time for that use had come.  On its chest, a powerful projection device whirred to life, accessing images stored in its databanks to create holograms, three-dimensional projections almost indistinguishable from the real thing.

Thomas would soon notice that the treeline was growing denser.  Were his eyes sharp enough, he might even catch new trunks and branches appearing out of nowhere.  None of these were real, mere illusions being generated by Johannes' powerful projection mechanisms- and yet to an outward observer, they looked the same, down to the tiniest detail.

Not only were these additional trees providing thick cover for Johannes, making his drone body far more difficult to spy, they also posed an indirect threat to Thomas himself.  With false trees now being projected around the area, it was only a matter of time until he tried to jump to one, only to find it was not real, likely resulting in a loud and painful crash.
