The Pike Ball is one of the three basic magic forms available at the item shop. Unlike the other two forms, it and its advanced versions remain active upon use and drain magic continuously. Refills are required to maintain the same Pike Ball for two minutes. Magic Potions cannot be used because using one will terminate an active Pike Ball. To earn this achievement, play "Battle Tower", which has a large number of enemies that can drop magic refills, as well as jars that always contain refills. Changing rooms with a Pike Ball active will not cancel it. The tower can be completed with the same Pike Ball. If available, also use the Magic Mode costume to reduce the rate at which the Pike Ball drains magic.
