Quarrels of (foo) slaying are missiles that can be fired with a Crossbow and posses slaying powers against appropriate monster type. They have default stats of (+3, 2d6+3) for most types and (+3, 2d8+3) for giant slaying quarrels. (Foo) can be one of the following monster types - jellies , demons, humanoids, constructs, undead, giants, and dragons. Each hit against the given monster type will grant a critical hit (with added +100% base damage for using proper slaying weapon, thus making final critical multiplier in the range from 3x to 6x). They are a specific missile type, and thus cannot have magic pre- or suffixes.
