Summon Magic

You are a mage that can summon beings or spirits with certain objects, the most common being celestial spirits. Although many summoning mages rely on their summons for fighting, some prefer to add their strengths to their current spirit or being they have summoned. The summoned anomalies tend to disappear after they have been defeated or used up their time or abilities and in most cases, their magic. Even though you can summon more than one at a time, the duration uses more magic, and may possibly end up killing you. But do not worry, you are the main character here, and the main author of this will try to prevent that as well, preventing heavy subjects and clearing up many things, and obviously edit in case any slide in. But back to the script, summoner type mages tend to have a Catalyst, an object that allows you to summon that spirit, whether it is a book, a key, maybe a card or whatever is possible, as long as that object is made for the intended use of summoning that spirit or being.
