  • "When you enter Gladiator Arena keep an eye out for Wolf! Able to smell fear and always going for the jugular, Wolf is 230-pounds of primal fury. He will ferociously defend his turf... and thrives on the opportunity to sink his teeth into any challenge."

  • From Wikipedia:

    a wolf tone, or simply 'wolf', is produced when a played note matches the natural resonating frequency of the body of a musical overtone that amplifies and expands the frequencies of the original note, frequently accompanied by an oscillating beating...which may be likened to the howling of the animal.

    Not to be confused with Wolfe Tone, a leader in the Irish independence movement of the late 18th century.
