Slaying ammunition refers to any missile that is guaranteed to inflict a critical hit on a target if the monster is of a particular type (e.g., a quarrel of humanoid slaying always land a critical hit on humanoid opponents). Missiles with the suffix 'of slaying' are regarded as separate items, with their own base damage stats. The suffix 'of slaying', on the other hand, is a generic suffix that can be found on any missiles including boomerangs and scurgari.
