Return Flight (Psionic)

: Note: Incorrectly listed in "Psychometablolic" in Dragon King. This is clarified on page 42 of "The Will and the Way" as a mistake.
This power lets the psionicist make a single missile automatically return if it misses its target. Any common missile weapon may be affected, from an arrow or crossbow bolt to a spear, chatkcha, sling stone, or even ballista bolt. The maximum weight of the missile is 10 pounds, so most catapult missiles are ineligible. The power relies on the aerodynamics of the missile, so unbalanced objects (chairs, mugs, small characters) don't work.
The psionicist must touch the missile and then fire it within two rounds— otherwise the power is lost. The psionicist must fire the missile, using his THAC0 for the attack roll.
If the missile is usually thrown, it returns to the psionicist's hand if it misses its intended target. If the missile is fired from a weapon, such as a bow or ballista, the missile returns and gently land at the psionicist's feet. This power removes the chance for an accidental hit on other enemies near the intended target—once the missile fails to hit the intended victim, it veers off for its return flight.
Power Score — The missile continues to home on its target, making a new attack each round with the psionicist's THAC0, without ever returning to the psionicist.
20 — The missile automatically misses the target and makes an attack instead on the psionicist, using his own THAC0!
