Secret Art: Lightning Field

You conjure a statically charged field around you, applying Static X where X equals your Focus x 3 to all enemies within 30ft of you. Enemies already afflicted by Static immediately take damage equal to 3 + half the static value. While within your Lightning Field, the Static on enemies is not removed at the end of their turn.

This field lasts until the end of your next turn.

Upkeep: You may pay 1 Mana at the start of your turn to repeat the initial effect and extend the duration of the field by 1 turn.
