Each of those groups have an opposing group. (i.e. Humanoid vs. Undead) Slayer Weapons will do double damage to the monsters they are meant for. Slayer Weapons can both be found as monster loot and be crafted by using a runic crafting tool. Slayer Spellbooks will cause most spells to do double damage to the monsters they are meant for. Slayer Spellbooks can only be crafted by scribes using a scribe pen. Slayer Instruments will increase your success chance by 20% when used on the creatures it is meant for. Slayer Instruments will decrease your success chance by 20% when used on the creatures from its opposing group. Slayer Instruments can only be found as monster loot. A successful use of a Slayer Weapon, Spellbook or Instrument will yield a little white flash on the monster.
