Ultra Giant Bull

Recombination Magic: Ultra Giant Bull (組替魔法『超絶巨大暴牛号』) is a Recombination Magic spell.

Description
With an open grimoire, the user takes control of a nearby larger structure and combines it into their magic house, creating an even more gigantic bull. This requires a large amount of magic power due to the amount of material being manipulated.

The process can be aided by the new parts being transmuted into the same materials as the magic house.
