The Mage Tower unlocks and enhances your spellcasters. Research 'Blizzard', 'Fireball', and 'Polymorph' here. Also, 'Far Sight' and 'Invisibility' for utility. The Gryphon Aviary offers 'Storm Hammers' for Gryphon Riders, significantly increasing their damage output. These upgrades are expensive but provide powerful tactical advantages, especially in later stages of the game. Don't neglect your spellcasters' potential.
