Millennial Tree Cookie extends his roots into the earthbread and transforms into the World Tree, dealing damage to enemies. In this state, he will dispel all debuffs applied to himself and gain the World Tree HP Shield that cannot be affected by Zap or Overcurrent. Millennial Tree Cookie will become immune to incapacitating effects and create a Sanctuary area where he will continuously restore allies' HP (except Safeguarded Cookies) and the World Tree HP Shield. Once the World Tree HP Shield is removed, the Sanctuary effect will weaken. Also, Millennial Tree Cookie will scatter Sacred Seeds at certain intervals, dealing damage and restoring his own HP or his World Tree HP Shield. After the end of the World Tree's duration, Millennial Tree Cookie will inflict the Equilibrium debuff upon the enemy from whom he received the greatest amount of damage during his transformation. If there are no enemies around Millennial Tree Cookie during his transformation, it will automatically cancel, and a portion of the remaining duration time will be deducted from his skill cooldown. If there are no Defense Cookies on the team, Millennial Tree Cookie will use Nature's Protection. As the source of all elements, Millennial Tree Cookie gains the Elemental Seer buff if there are Cookies of 4 or more different elements on the team. Also, during his transformation, he will grant the Elemental Force buff to the team. If the Cookies are the Guardians of Nature, they will receive a stronger Elemental Force: The Guardians buff. At the beginning of the battle, Millennial Tree Cookie will gain the Majesty of Eons buff.
