Magic
World Tree Magic: Siegfried uses this form of magic to generate and manipulate trees.
Magic Tree Descent 「魔樹降臨 Maju Kōrin」: With an open grimoire, the user calls forth the roots of a giant tree from the clouds overhead. From these roots, the user could craft a multitude of wooden objects, including broomsticks. Once the user is done, the roots retreat back up into the clouds.
World Tree Magic: Great Tree Misteltein 「世界樹魔法『ミスティルテインの大樹』 Seikaiju Mahō "Misutirutein no Taiju"」: With an open grimoire, the user spreads roots over a wide area. These roots absorb the mana of everyone within the area.[2] Once enough mana is absorbed, the user creates a large tree that can capture the enemy and engulf a city.
World Tree Magic: Misteltein Seed 「世界樹魔法『ミスティルテインの種』 Seikaiju Mahō "Misutirutein no Tane"」: With an open grimoire, the user throws a seed at a target. The seed drains the target's magic and rapidly grows into a large tree around the target, immobilizing them.
