Required Level: 30
Details: Lightning Mastery works just like Fire Mastery; by substantially boosting the damage of every skill in the skill tree. Maxing this one out is a priority for most Lightning Sorceresses.
- In early versions of the game, Lightning Mastery instead reduced the mana cost of lightning spells. At that time, each of the three masteries were unique.
