Notes and trivia

This talent is named after Lord Marrowgar's ability Bone Storm.
When cast, Bonestorm consumes up to 100 Runic Power to determine its duration. Runic Power gained after casting does not increase an already-active Bonestorm's duration.
If the amount of Runic Power consumed isn't a multiple of 10, there will be an "extra" tick at the end that deals less damage, so that no Runic Power is wasted. For example, a Bonestorm that consumes 45 Runic Power will deal normal damage 4 times, then partial damage once.
This talent was mentioned in the April Fools' Day Legion Alpha patch note preview: "Because we're tired of hearing you shout it on voice chat all the time, Bonestorm has been renamed 'Swirly Body Sticks.'"
