There are school spells. School pets. School castles. Why not have school dungeons? Each dungeon will be made specifically for each school so that every wizard can be challenged. Here are some of my ideas: - dungeon could include spamming infections/life dispels/ etc. to prevent healing - dungeon could use earthquakes and shatters often to give myth students a taste of their own medicine - dungeon could have high health and constant healing, because you know how storm has that incredible damage - dungeon could have high damage and critical to bring down the student's high health - dungeon could use smoke screen often to hold back the wizard's strong attacks - dungeon could have big over time attacks to challenge the student's variety talents - dungeon could include mana burn because balance students like to stock up on pips to have a strong attack (like Judgement )
