Spell Mastery
Most believe that a spell is mastered the moment it is memorized. The oldest arcanists laugh at such certainty. To cast a spell is only to borrow its power. True mastery begins only after the spell has watched its caster through countless victories, failures, sacrifices, and impossible odds. In time, the magic itself begins to remember the soul that wields it.
The scholars of the Perky Crew were the first to record this strange phenomenon. They discovered that every spell carries an echo left behind by those who cast it. Each repetition strengthens that echo, reshaping the spell until it responds not merely to words and gestures, but to instinct itself. Flames burn hotter without command. Wounds mend beyond expectation. Protective wards linger longer than their creators ever intended. No two masters awaken the same potential, for every hero leaves a different mark upon the Weave.
