The script below is a modified version of the default OnHit creature script in the game (nw_c2_default6). It has a 1 in 3 chance of making a missile (arrow, bolt, dart, shuriken, throwing axe) recoverable from a creature's corpse when it dies.

Currently sling bullets are disabled, since they're more likely to bounce off than get lodged in a creature. Those lines can be uncommented if required (see the switch in the CatchAmmo function).
