Skyrim – walkthrough and progression.

It seems there's a correlation with how much mana a spell consumes. Equilibrium doesn't consume any.

I'll need to check that. By the way, it seemed to me that if you take a skill of a certain level (Apprentice of Destruction Magic or Specialist Thief), then spells or castles of that level yield less experience.

P.S.: I searched the entire Labyrinth, found one dungeon, searched it, and didn't find the spell :(.
