In addition, while attuned to the clubs, when you are holding both clubs and cast shillelagh, the cantrip imbues both clubs with nature's power for the one minute duration. Per the cantrip, you may use Wisdom for attack and damage rolls for each club and each weapon's damage die becomes a d8.
Myra Windsong, a Druid of the Blue Rose Circle, was awarded these magical clubs from the Great Auk of the Western Horizon. He bore witness to her moment of need as she battled a scouting party for the Bone-Eater Legion of hobgoblins, all alone, battered and unarmed. The Great Auk of the Western Horizon transformed two branches of a nearby ceil tree into magic bludgeons, allowing Myra to defeat the scouts and warn her Circle.
