Sigil of Power is a spell which places a sigil in an area around the caster for a duration. The sigil grants added lightning damage to friendly units. Spending mana while within the sigil empowers it, increasing the buff effect and when full powered, causes enemies within the sigil to deal less damage.

Skill functions and interactions

Each skill usage within the area can only increase the number of stages by one, regardless of Mana spent.
