Details:

  One of the many Hunting Titles recorded in the Terra Sol World System and the second-most common one after [Monster Slayer].

  Hunting Titles come in three stages: Slayer, Slaughterer, and Genocider. By killing a variable number of creatures with the same trait, one will unlock these titles.

  However, killing lower-ranked creatures will not count for these titles, and even if you kill creatures that are of a higher racial rank than you, you still need to kill quite a number of them anyway.

  [Beast Slayer] is the title that is obtained by killing creatures with ANY Beast-type traits. This includes creatures that would otherwise unlock other titles such as [Rabbit Slayer] or [Wolf Slayer].

  The Ability skill provided by [Beast Slayer] is [Stamina]. It represents animals' endurance needed to live in the wild, even if it's not appreciated by people who specialize in the Hunter class. [Stamina] is a skill obtainable from the Scout class after all, so people with Hunter, a scout-line class, as their Main Class, would already own the [Stamina] skill thanks to Scout.

  Garami's comment: ...just wondering, do demons have something like this?

  K-N's comment: Correct. But it is advised to become so strong that people cannot hunt you over being so weak that people do not bother with you.

  Garami's comment: Be so VIP-ish that common thugs can't get me? I can live with that.
