Here’s a draft of a PRF Weapon feature for a TTRPG (like D&D 5e / Pathfinder), written in professional game design style.

To replicate this on a generic unit, you would need three or four premium skill slots. That is the PRF weapon advantage.

Unique Utility: These weapons often grant abilities that standard gear cannot, such as the Wing Spear (effective against armor/cavalry) or the Brave Lance, which allows for multiple attacks.

You're referring to the PRF (Precision Rifle Folder) weapon!

  1. Mid-Course Guidance (Inertial + Update): The missile flies toward a predicted intercept point using data from the launching aircraft’s radar, which operates in Medium PRF. No seeker activation yet.
  2. Seeker Activation (Medium PRF): At a predicted distance (e.g., 15–20 km), the AMRAAM’s seeker powers on in a Medium-PRF mode. It searches a narrow cone for the target’s Doppler signature, filtering out ground clutter.
  3. Terminal Homing (Adaptive PRF): As the missile closes, its PRF dynamically increases to maintain unambiguous velocity tracking. In the final seconds of an intercept, the seeker may transition to a very high PRF-like waveform to resist chaff and jamming.
