Trivia

  • They appear to use all attack styles when using melee, depending on the animation they use: slashing when they use their talons, stabbing when they jab with their tail and crushing when they bite the target.
  • Upon release, the wyvern's Defence level was 120. This was reduced to 90 in an update on 18 January 2018. This also changed its combat level from 159 to 152.
  • Upon release, Long-tailed Wyverns only dropped a maximum of 6 seaweed spores. This was increased to 12 in an update on 12 July 2018.
