Ahriman's Drones are the enemies native to The Prince's Time Line.
The drones have no projectile properties, so they are limited to close-range combat. However, what they lack in long-range capabilities, they make up for in endurance and physical strength. If your fighter has any long-range capabilities or is carrying a long-range weapon, I suggest you use it. Otherwise, the Smash-and-Dash method(where you get in close, inflict as much damage as possible and then run back) is a good method as the slow-moving drones are just as slow to react.
