The requirements in order to summon Phosphora's Spirit.
Summon is an option within the Collection tab of the Spirits single-player mode that allows players to summon certain spirits with cores obtained by sending spirits home in the Dismiss menu. Some spirits are only obtainable through this method, meaning the only way to collect the total number of spirits is to summon some of them. Previously summoned spirits may later appear on the Spirit Board, and others can be encountered in World of Light without needing to summon them first. There are currently 133 summonable spirits, 91 of them are summon-exclusive, and of which, 15 of them can appear on the Spirit Board after the first summon.
How to Use
Each spirit has a certain amount of cores and SP required in order to summon it. Often, the type of cores needs to be specifically from a certain spirit. For example, summoning a Paper Mario spirit consumes a Cut Man spirit and Cardboard Box spirit, along with any Neutral type spirit.
The player may also directly use spirits in summoning, rather than dismissing them first and then summoning. The game will automatically dismiss the chosen spirits (gaining SP for the dismissal) and use those cores for summoning.
