Mage Guild spell restrictions by factions – Heroes 3 Complete and Horn of the Abyss
Mage Guilds are structures that teach heroes new spells, refill hero’s spell points when they stay overnight in town, and the place where heroes can acquire a spell book.
For each level, a random set of spells becomes available at the guild, based on the given town’s natural probabilities and restrictions for specific spells. For example, Inferno towns have higher odds of having fire school spells or Animate Dead cannot be found anywhere else except in Necropolis. Fortress has one very strange restriction….
Of course, heroes can learn restricted spells in Mage Guilds of other factions.
