Chain of Words

You see the thin lines of magic between your creations, and you can exploit that connection with a small shift of power from one rune to another. You Invoke two Runes within 60 feet. In addition to the runes' normal effects, a chain of glowing script flows between them, dealing (half your level (minimum 5))d6 force damage to all creatures in a straight line between them with a basic Reflex saving throw; creatures bearing the invoked runes are not in the area of this line. A creature who critically fails its save is also Immobilized for 1 round or until it Escapes, as the runes seal its movements. The DC to Escape is your class DC. At 12th level, and every 2 levels thereafter, the damage increases by 1d6.
