# Guild Spells Guild spells are support cards that the player can use in real time as the heroes are battling. Attack the enemy with a fire spell, create a magic shield on one of your heroes, decrease the attack damage to a group of enemies and much more... Guild spells can be bought from the guild shop or from the city magic school. They come in packs with random spells. Spells can be upgraded when duplicates are found. Upgrading the guild will unlock new packs and high chance rate for rare spells. --- # Agent Instructions: Querying This Documentation If you need additional information that is not directly available in this page, you can query the documentation dynamically by asking a question.
